Abstract:

The groundwater can cause a significant threat to the safety of the tunnels excavated in water-rich areas. To investigate the impact of seepage to tunnels, the most important issues are calculations of the saturated surface and seepage flow. According to the great similarity between temperature field and seepage field in the theoretical foundation, differential equations and boundary conditions, the thermal analysis function of ANSYS could be used to calculate the non-pressure stable seepage based on the iteration method. The saturated surface and seepage flow through the lining are obtained b

Abstract:

A mathematical model of flow on a sloping breakwater face is described and results of calculations compared with some experimental results to show how the model can be calibrated. Flow above the surface of the slope is represented by the shallow water wave equations solved by a finite difference method. Flow within the breakwater is calculated by one of two methods. A solution of the linear seepage flow equations, again using finite differences or a simplified model of inflow can be used. Experimental results for runup and reflection coefficient are from tests performed at HRL Wallingford.

Abstract:

Vacuum tube dewatering method and light well point method have been widely used in engineering dewatering and foundation treatment. However, there is little research on the calculation method of unsaturated seepage under the effect of vacuum pressure which is generated by the vacuum well. In view of this, the one-dimensional (1D) steady seepage law of unsaturated soil in vacuum field has been analyzed based on Darcy’s law, basic equations, and finite difference method. First, the gravity drainage ability is analyzed. The analysis presents that much unsaturated water can not be drained off only

At present, there are two main methods for solving oil and gas seepage equations: analytical and numerical methods. In most cases, it is difficult to find the analytical solution, and the numerical solution process is complex with limited accuracy.

The quasi-Newton method is used to solve the nonlinear equations. The solutions of the nonlinear equations with an infinite outer boundary, constant

Abstract:

Cofferdam is a building in the form of earth, stone, concrete or masonry filling and holds water, prevents flooding, provides irrigation. The building has many functions such as for agriculture, power generation, and tourist attractions. Cofferdam will also be very helpful in flood control which will control flood water so that it will not overflow excessively which endangers the surrounding community. Besides having great benefits. If the cofferdam collapses (broken) it will cause flash floods that result in casualties. Therefore the cofferdam must be designed safely and technically feasible.

Abstract:

Seepage damage has been one of the most important factors that affect the safe operation of embankment dams, So more consideration is taken into the saturated soil more than non-saturated soil. In this paper, we carry on the experiment by using SEEP/W software to take the flow field analysis of unsaturated soil of the core embankment dam. Based on the experiment, we analyzed the normal water level of dam seepage line, checked the flood level lower position, the pressure and the flow hydrodynamic calculations of the dam such as hydraulic slope, analyzed different water seepage under the dam cha

Abstract:

As the coastal region is the most developed region in China, an increasing number of engineering projects are under construction in it in recent years. However, the quality of these projects is significantly affected by groundwater, which is influenced by tidal variations. Therefore, the regional groundwater dynamic characteristics under tidal impact and the spatiotemporal evolution of the seepage field must be considered in the construction of the projects. Then, Boussinesq function was introduced into the research to deduce the seepage equation under tidal influence for the coastal area. To

Mountain-front recharge, including mountain block recharge and stream seepage, is important for basin aquifers. With the construction of reservoirs in mountainous areas and the recurrent seepage problems of dams, reservoir seepage might become another type of mountain-front recharge. This study identified the recharge sources of groundwater beneath Huangbizhuang Reservoir on the North China Plain (NCP). Hydrochemical data and the stable isotopic compositions (δ18O and δD) of water were employed to determine the occurrence of Huangbizhuang Reservoir seepage recharge to groundwater in the mounta

Data assimilation for unconfined seepage analysis has faced significant challenges due to hybrid causes, such as sparse measurements, heterogeneity of porous media, and computationally expensive forward models. To address these bottlenecks, this paper introduces a physics-informed neural network (PINN) model to resolve the data assimilation problem for seepage analysis of unsaturated earth–rockfill dams. This strategy offers a solution that decreases the reliance on numerical models and enables an accurate and efficient prediction of seepage parameters for complex models in the case of sparse

Introduction. Due to intensified construction in the areas of loess subsiding soils, the issue of forecasting the evolvement of underflooding processes is becoming a relevant objective, since these processes can cause the emergency seepage, uneven groundwater surge, change of the soil stress-strain state and, as a result, impossibility to operate the buildings or structures. Loess soils are attributed with the distinct anisotropic permeability. Subsidence and water infiltration take place in condition of incomplete water saturation.

Abstract:

Drainage pipes are often positioned downstream of embankments to mitigate pore pressure, thereby reducing the risk of dam failure. Considering that the size of drainage pipes is much smaller than that of embankment dams, directly discretizing the drainage pipes will generate a huge number of elements. Therefore, this paper proposes a seepage element containing drainage pipes. In this element, the permeability of the drainage pipe is taken as the third type of permeable conductivity condition, and it is considered in the energy functional.

In this research, a two-dimensional analysis of transient seepage and sediment transport in diaphragm walls for coastal protection projects was conducted using the finite element method. One of the key factors influencing the stability of diaphragm walls in coastal protection works is transient seepage and sediment transport (flow boundary conditions). The reduction of passive soil resistance due to seepage and sediment movement can lead to stability issues through piping and scour effects. A representative soil profile from the Niger Delta region was subjected to transient seepage (long-term
