In this study, closed-form solutions are presented for two classical problems: the load exerted on strip or circular trapdoors and stability of tunnel headings in purely cohesive soils, considering both case a constant undrained shear strength linear vertical profile. The based minor modification Gunn's lower-bound plasticity solution. According to comparative numerical stress analyses finite-e...

Solutions for the point force and line load suddenly applied in a linear elastic fluid-infiltrated porous solid are rederived in a manner that emphasizes the relation to solutions for the homogeneous diffusion equation. Specifically, the stress, displacement, and pore pressure due to instantaneovs and continuous injection of fluid mass are obtained. These are differentiated to yield solutions f...

This study focuses on investigation of the undrained shear strength unsaturated frozen silts prepared at varying initial thermal and hydraulic conditions. The degree saturation controls ice unfrozen water contents temperatures below depression point. properties soils are highly influenced by which is coupled with state soils. To evaluate silts, a series direct simple experiments were performed ...

This study applies artificial neural networks (ANN) to simulate the soil stress-strain relationship observed in test data from triaxial shear testing of saturated sand. A genetic algorithm is used to obtain an optimal framework for the ANN. The results show that the proposed genetic adaptive neural network (GANN) can effectively model undrained monotonic and cyclic triaxial behaviour of saturat...

A study is made of the problem of interpreting the results of Menard pressuremeter tests on soil in situ. In the test a cylindrical cavity is expanded by internal pressure, and the relation between applied pressure and cavity vulume change is measured. It is shown that the results of a single test are enough to determine a complete stress-strain relation in plane strain, and a simple graphical ...

In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...
