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 ...

The settlement behavior is a common problem on the railway structure that can be optimized by applying cement-treated soil as ground restoration. However, application of high cement mixing content needs proper estimation achieved adjusting element testing. strain measurement devices estimate deformation characteristics, such secant modulus, Poisson ratio, and shear modulus describe stiffness so...

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 ...
