Foundations bearing capacity subjected to seepage by the kinematic approach of the limit analysis

Mehdi VEISKARAMI, Ghasem HABIBAGAHI

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 4,   Pages 446-455 doi: 10.1007/s11709-013-0227-5

Abstract: An estimate of the ultimate load on foundations on soil layers subject to groundwater flow has been presented. The kinematic approach of the limit analysis was employed to find the upper-bound limit of the bearing capacity. Both smooth and rough base strip foundations were considered associated with different collapse patterns. Presence of the groundwater flow leads to a non-symmetric collapse pattern, i.e., a weak side and a strong side in two-sided collapse patterns, depending on the direction of the flow. It was found that the bearing capacity has a decreasing trend with increase in the groundwater flow gradient and hence, a reduction factor has been introduced to the third term in the bearing capacity equation as a function of the flow gradient.

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 2,   Pages 237-245 doi: 10.15302/J-FASE-2017135

Abstract: Quantification of seepage in disconnected river-aquifer systems is significant for local water managementMFSL can calculate the stable seepage rate by assessing the dominant low permeability layers (includingWe used MFSL to calculate local seepage rate, and used GIS to extend the results to a regional scale.Results showed that low permeability liners could greatly reduce the seepage rate.However, if an unlined inundation area exists, the seepage rate may increase greatly.

Recent development in biogeotechnology and its engineering applications

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5,   Pages 1073-1096 doi: 10.1007/s11709-021-0758-0

Abstract: Microbial geotechnology or biogeotechnology is a new branch of geotechnical engineering. It involves the use of microbiology for traditional geotechnical applications. Many new innovative soil improvement methods have been developed in recent years based on this approach. A proper understanding of the various approaches and the performances of different methods can help researchers and engineers to develop the most appropriate geotechnical solutions. At present, most of the methods can be categorized into three major types, biocementation, bioclogging, and biogas desaturation. Similarities and differences of different approaches and their potential applications are reviewed. Factors affecting the different processes are also discussed. Examples of up-scaled model tests and pilot trials are presented to show the emerging applications. The challenges and problems of biogeotechnology are also discussed.

Stable expression and control parameters in the numerical simulation of unsaturated flow

Zhiyuan ZHANG; Xu LI; Yongkang WU; Xiaokang LI

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 12,   Pages 1501-1514 doi: 10.1007/s11709-022-0893-2

Abstract: The Richards’ equation describes the flow phenomenon in unsaturated porous media and is essential to hydrology and environmental science. This study evaluated the numerical stability of two different forms of the Richards’ equation. Sensitivity analyses were performed to investigate the control parameters of the equation. The results show that the h-form Richards’ equation has better applicability for calculating variable saturation flows than the θ-form Richards’ equation. For the h-form Richards’ equation, the hydraulic conductivity of the soil in the low-suction range and the specific moisture capacity in the high-suction range primarily influenced the solution. In addition, sensitivity analyses indicated that the saturated hydraulic conductivity, initial condition, and air-entry pressure have a higher sensitivity to the simulation results than the saturated water content, rainfall intensity, and decline rate of hydraulic conductivity. Moreover, their correctness needs to be guaranteed first in numerical simulations. The research findings can provide a helpful reference for improving the reliability of numerical simulations of unsaturated flows.
