Finite-Element Approach to the Erosion and Transport of Fine Particles in Granular Soils
Publisher: American Society of Civil Engineers
Abstract: The increase of the water table level presently occurring in the city of Milan led to some leakage of groundwater in underground facilities and subway tunnels. These structures, in fact, were completed about three decades ...
Finite Element Modeling of the Time-Dependent Deformation of a Slope Bounding a Hydroelectric Reservoir
Publisher: American Society of Civil Engineers
Abstract: The south slope of the Vernago hydroelectric reservoir in northern Italy is subjected to a slow time-dependent movement that produced some structural damages in a service shaft located within it. With their continuation, ...
Back-Analysis Approach for the Design of Drainage Systems
Publisher: American Society of Civil Engineers
Abstract: The geotechnical design of drainage or dewatering systems requires a free surface seepage analysis to evaluate the water flux that corresponds to the sought lowering of the water table. It is observed in practice that ...
Numerical Evaluation of the Surface Displacements due to Soil Grouting and to Tunnel Excavation
Publisher: American Society of Civil Engineers
Abstract: The low-pressure grouting with cement mixtures is one of the techniques adopted for improving the mechanical characteristics of granular soils prior to the excavation of underground openings. When applied to shallow subway ...
Influence of Boundary Conditions in a Finite-Element Analysis of River Levees
Publisher: American Society of Civil Engineers
Abstract: The effects of boundary conditions on the stability of a river levee built on a low-permeability soil layer overlying a coarse-grained deposit were studied by using the finite-element method (FEM). The FEM analyses could ...
Seepage-Induced Erosion in Granular Soil and Consequent Settlements
Publisher: American Society of Civil Engineers
Abstract: The erosion of the fine fraction of granular soils due to seepage is a possible cause of the settlements of shallow foundations. Here the problem is tackled with reference to deep pumping wells to be installed in an urban ...
