Abstract:
The effects of polypropylene fiber reinforcement on shear strength and unconfined compressive strength of silty soft soil in tidal flats were studied. Through shear test and unconfined compression test, Experimental study was conducted on silty soft soil of allene fiber reinforced beach with 0~0.6% different mass content and 3 ~18m different length. The failure process and mechanism of fiber reinforced soil samples were also discussed. The test results show that: Shear strength (cohesion and internal friction Angle) and unconfined compressive strength increased rapidly in the early stage with

In the southwest of China, there are widely distributed expansive soils. However, to save costs and manage the speed of construction, these shallow expansive soils are often filled with subgrade materials. Therefore, it is necessary to clearly understand the mechanical behaviors of unmodified shallow expansive soils. Current research on the mechanical behaviors of shallow expansive soils is mainly focused on shear and compressive strengths but rarely on the tensile strength since general tests are costly, time consuming, and difficult to conduct. Therefore, uniaxial tensile, unconfined compres

The undrained shear strength usually is determined from unconfined compression test or from triaxial compression test.

Clay soil has low load-bearing capacity. One method to improve this issue is by mixing chemical additives, such as silica fume and red brick powder, into the clay soil as adhesive media that can fill the soil's pores, compacting and forming a solid mass. This study aims to determine the unconfined compressive strength and shear strength of clay soil after adding silica fume and red brick powder. The method involves testing unconfined compressive and shear strength using 9% red brick powder by soil weight, along with silica fume added in varying amounts of 5%, 10%, and 15%.

Abstract:
Abstract Advanced rock mechanical characterization of a giant Cretaceous carbonate field in Abu Dhabi is the focus of this paper, that not only focused on routine triaxial tests for shear strength estimates but also to understand pore collapse, tensile strength, thermal and creep behavior of these rocks. The approach has started with auditing and selection of core intervals from various offset wells. These core intervals are selected to represent lateral and vertical coverage of various sub-units within various reservoir and caprock intervals. Scratch tests and whole core CT scans are conducte
