Abstract:
Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests on DCIS piles in the literature to verify the assumption that they behave as large displacement piles. In particular, the shaft resistance of DCIS piles in sand is uncertain due to the complex interaction between the freshly cast concrete and surrounding displaced soil after extraction of the steel installation tube. This paper describes the installation, curing, and mainta

Abstract:
Piles are provided to carry large loads coming from superstructures to the soil. During pile installation resistance developed either at the pile tip or along the surface of the pile. Based on that the piles are classified as either end bearing piles or friction piles. As per Indian Standards bored cast in-situ piles are designed using the methods taken from IS 2911 (part 1/sec 2): 2010. Ultimate load carrying capacity of pile can also be computed from the equation suggested by Mayerhof. Vesic’s equation is helpful for the analysis of laterally loaded piles.

Through the above work, the author found that order 3 polynomial fitting model is the most reliable model for fitting Q-s curves of piles with expanded branches and plates when bearing pressure or uplift load. In order to improve the accuracy and reliability of the fitting and forecasting, multi-model should be used.

With the rapid development of modern science and technology, the hole-making technique of punched cast-in-situ piles has also developed rapidly. As punched cast-in-situ piles still belong to the indirect hole-making perfusion, which is elusive, it is difficult to find out problems happening during the construction process. And these problems tend to cause very serious results.

The existence of residual stresses locked-in prefabricated displacement piles is a well-known problem and has been addressed by a number of researchers in the last decades. This is not the case with cast in situ piles: as a consequence of concrete curing, pile-soil interaction starts soon after concrete casting, causing stress changes in terms of both normal and shear stresses. Such circumstance has been confirmed by few experimental evidences, reported in the paper, in saturated or dry soil conditions.

It is considered that the reliable method for finding bearing capacity is pile load test, which is time consuming and costly.

Abstract:
A series of laboratory and field tests were performed to evaluate the applicability of an optical fiber sensor system in the instrumentation of piles. A multiplexed sensor system, constructed by arranging several Fiber Bragg Grating (FBG) sensors along a single line of optical fiber, is capable of measuring local axial strains as a function of wavelength shifts. The distributions of axial load in three model piles and a field test pile evaluated from the strains measured by FBG sensors are found to be comparable, in terms of both magnitude and trend, with those obtained from conventional strai

Abstract:
Combined with practical engineering application, the test researches were carried out to analyze the soil compacting effects of Cast-in-situ concrete pipe pile while the pile was driven by vibration hammer. This article is focused on the characteristics of soil uplift and lateral deformation around pile, included surface soil and deep soil. In addition, the change characteristic of pore water pressure of soil around pile is also analyzed, and some useful rules were concluded. All researches are helpful to optimize the construction parameters, such as distance between piles, pile diameter etc.,

Abstract:
The present work stems from the design of a viaduct in South Wales, U.K., where full-scale pile testing was carried out to assess whether the proposed design methods would meet the required load capacity and settlement criteria for the working piles. Five fully instrumented large diameter bored cast in situ piles, up to 30 m deep, were installed in weathered mudstone and tested under vertical loading. A sixth pile, which had no shaft instrumentation, was formed with a voided toe. In conjunction with vast soil data from 218 site investigation boreholes, the extensive data produced from the load

Abstract:
Controlling the river regime in the lower wandering reaches of the Yellow River Basin is important for ecological protection and high-quality development. This study reviews the development of pile groynes suitable for wandering rivers. As a widely used form of reinforced concrete pile, pile groynes, including round and sheet piles, have been built in alluvial rivers in large numbers for many years. Currently, research focuses on improving the stability and erosion resistance of these piles. Here, three types of groynes are discussed according to the construction technology: cast-in situ bored

Abstract:
This paper presents some aspects of the design of two new bridges over the River Vardar in Skopje. "Mihajlo Apostolski" is an integral bridge, consisting of two separate structures (22.05 + 50.50 + 21.05 m = 93.6 m length and 15.3 m width). The bridge deck is made up of a two-cell prestressed cast-in-situ box girder with a parabolically variable cross section. The abutments and the piers are wall-shaped and supported on single and double row piles, respectively. The side spans, together with the approaching structures, were proposed to be built on traditional scaffolding, while the middle span
