WebInitial shear stress is crucial in the three-dimensional (3D) behaviors of soil–structure interfaces but has seldom been examined. This research presents 3D monotonic and cyclic behaviors of a gravel–structure interface, considering initial shear stress from large-scale direct-shear tests. WebLIQUEFACTION BEHAVIOR OF SAND-GRAVEL COMPOSITES This paper describes a series of undrained cyclic triaxial tests to quantify the effect of gravel content on the liquefaction resistance of sand-gravel composites. Specimens with gravel contents of 0, 20, 40, 60, and 100 percent were tested.

WebABSTRACT Responding to the increasing need for determining the strength and deformation characteristics of gravels in situ, an improved method of sampling by in situ freezing to obtain a high quality undisturbed sample of saturated gravel from a depth of about 20 m below the ground surface was developed. WebIn common practice, the strength of the soil is defined as the peak strength (Points a and b in Figure 12-3) measured in the test. When this is used in a stability analysis, the tacit assumption is that the peak strength is attained simultaneously along the entire rupture surface.
