1+170 in April 2003. Investigating the causes and mechanism of this slope failure along with suggesting a proper stabilization technique is aimed in this study. For that purpose, a detailed site investigation study, including engineering geological mapping, drilling work, in situ and laboratory tests, was performed. Weathered tuffite, tuffite, flysch and dacitic tuffite, from top to bottom, are the major units in the study area. A &ldquo
translational slide&rdquo
occurred in completely weathered tuffite owing to the disturbance of the stability of the slope by the excavations performed at the toe of the slope
particularly the foundation excavation for the restaurant building and for the road cut for the Giresun &ndash
Espiye road. After establishing the model of the landslide in detail, shear strength parameters of the failure surface were determined by the back analysis method as "
cohesion"
=2.5 kN/m2 and "
friction angle"
=9°
. Toe buttressing, ground water and surface water drainage options were considered for stabilizing the slope. For the back analysis calculations, the Morgenstern-Price and Spencer methods were used with the aid of the SLOPE/W computer program.

k Road at KM: 72+000-72+200 in an ancient landslide area. For this purpose, the geotechnical parameters of the mobilized soil along the slide surface was determined by back analyses of the landslide at four profiles by utilizing the Slope/W software. The landslide was then modeled using coupled analyses (with the Seep/W and Slope/W softwares) along the most representative profile of the study area by considering the landslide mechanism, the parameters determined from the geotechnical investigations, the size of the landslide and the location of the slip circle. In addition, since the study area is located in a second degree earthquake hazard region, pseudo-static stability analyses using the Slope/W software were performed incorporating the earthquake potential. The most suitable slope remediation technique was determined to be a combination of surface and subsurface drainage, application of rock buttress at the toe of the slide and unloading of the landslide material. A static and dynamic analyses of the landslide was also performed through utilizing finite element analyses. The static analyses were calibrated using the inclinometer readings in the field. After obtaining a good agreement with the inclinometer readings and finite element analyses results, the dynamic analyses were performed using acceleration time histories, which were determined considering the seismic characteristics of the study area.

This study established the numerical model of Shi-Shui-Keng landslides (S-S-K landslides) using TALREN-4 numerical tool according to the field investigations and the in-situ monitoring such as the geological boring data, the instrumentations of inclinometer and the records of groundwater level. In addition, a series of stability analyses were carried out on the S-S-K landslides remedied by various construction plans. Based on the numerical results of stability analyses, the failure mechanism of sliding surface can be captured. Subsequently, a systematic parametric study was performed on the design variables of two stabilization methods, namely, pile wall and anchor to examine the possible influence of the design variables on the potential sliding surface. It was found that to stabilize a large scale of landslides the slope stability can be significantly enhanced if the rigid-type of pile wall is adopted as the stabilization method. According to the numerical results of parametric study on the design variables of stabilization methods, the following conclusions can be drawn. The installation parameter Rx=0.5 can give the optimum location for pile wall to penetrate the sliding surface and obtain the most effective enhancement to the slope stability. On the other hand, for a specific installation angle of anchor

In order to investigate the impact of subsurface drainage behavior of the drainage wells on the slopes stability and its stability mechanism. In this study, the three-dimensional numerical finite element method is used to simulate the drainage efficiency of the drainage wells in the large landslides and the mechanical mechanism of the drainage wells. The research is divided into two groups: The first one is to set up drainage wells in a large landslides to evaluation drainage benefit assessment. For large landslides, according to the current collection of drilling data, topographic contour , geological maps, hydrogeological maps, soil/rock laboratory tests, grond movement and groundwater monitoring and other relevant information. It can be used to establish a 3-D numerical model of large landslides, and three models are built to explore four drainage wells. Subsequently, the #1, #2 drainage wells use the groundwater level monitoring value of the 2016 Meiji typhoon rainfall event as the storm water level, and the #3 and #4 drainage wells use the groundwater level monitoring value of the August 23, 2018 rainstorm event as the heavy rain. The water level, and the steady-state drainage analysis under normal and storm water levels, to explore the underground drainage capacity of the drainage wells, and the impact on the groundwater drawdown and slope stability. The potential sliding surface of the simulation results is roughly in agreement with with those from observation. At the same time, #3, #4 drainage wells the bottom horizontal drains regularly show a most efficient discharge rate, however the length of the horizontal drains of #1#,#2 drainage wells’ efficiency cannot be summarized . Due to the restrictions on land use, the drainage wells cannot be placed in the most appropriate position, but they still have the drainage effect they deserve. The new drainage wells flowmeter can be compared with the analog value in 2018. In addition, the calculation of the deformations and failure behavior of the drainage wells shows that the drainage wells are deeper than the colluvium entering into sandstone layer, the deformations and compressive stress during drainage are much larger than those without crossing the sandstone, causing damage to the drainage wells . For the planning of the location of the later drainage wells, it is recommended to collect certain drilling datas first, or to design a bracket inside the wells body to provide sufficient pressure resistance

Chai-San is the back garden of Kaohsiung city. It was a military control area in the early stage, enjoying the beauty of the mountains and the sea, making the local tourism. The shallow layer is a Coral Reef in the Chai-San Area. The deep area is formed by the discontinuous surface of Mudstone, which is a very special topography and geological structure. Over time, the formation and displacement of the strata are caused by the waves sweeping beneath the slopes. According to the monitoring data showed that the landslide will be accompanied by heavy rain. The rainfall duration in Chai Shan region is mainly between May and October each year. Landslide presumably because of the concentrated rainfall, Strata are subjected to rainfall infiltration, resulting in higher groundwater levels, resulting in a weakening of the mudstone layer itself or the interface with limestone.Caused the Chai-Shan Landslide displacement toward of the Western finally. This study compiled the local Landslide Rainfall Drainage remediation materials and the Kaohsiung City Government and the Landslide monitoring data (from 2012 to 2015), the effectiveness of the project is compared with the formation slip data and the Rainfall data. The effectiveness of the treatment is discussed comprehensively, and the future management plan can be provided as a reference.
