This paper presents a new algorithm for assessing the reliability of three-dimensional (3D) slope stability considering spatial variability soil based on Particle Swarm Optimization (PSO) algorithm. First, 3D random field is generated using Karhunen–Loève (K-L) expansion method. Then, simplified Bishop method limit equilibrium coupled with PSO to calculate safety factors slope. Finally, failure probability determined Monte Carlo Simulation After validating rationality proposed through...
This paper presents a novel method of treating high water content dredged slurry by vacuum pre-pressure using woven rice straw as horizontal drainage boards (SHDs). not only helps to avoid the impact plastic on environment, but also utilize agricultural related waste. The study aimed investigate effect SHDs degradation transfer within and consolidation characteristics slurry. Indoor preloading model tests were conducted soil settlement, degradation, variation distribution board. results show...
The direct application of the Hoek–Brown failure criterion to practical slope engineering is still an urgent problem. geometries and earthquake effect need be considered in determination linear Mohr–Coulomb (MC) strength parameters from criteria for stability analysis. This study adopted tangential method construct a three-dimensional (3D) rotational mechanism using homogeneous rock slopes undergoing earthquake. quasi-static was employed treat seismic action as external force work–energy...
Slope slip surface plays a vital role in the prevention and control of landslide hazards. For homogeneous soil slopes, three-dimensional (3D) limit analysis method was used to analyze slope critical surfaces with nonlinear strength envelope.

In actual engineering, cyclic loading, such as wave multi-directional seismic and traffic involves the continuous rotation of principal stress axis in ground. A series consolidated-undrained torsional shear tests was performed on large, hollow cylindrical specimens, using a cylinder apparatus (HCA), to investigate undrained deformation behavior degradation natural soft marine clay from Wenzhou, China. The test results obtained this study showed that response saturated strongly influenced by...
Cracking from soil desiccation is a common phenomenon. Understanding the structure of cracks highly important in research moisture and heat transportation, as well strength within soil. There limited on three-dimensional (3D) spatial characteristics cracks. Furthermore, absence dependable precise in-situ technique for extracting digitizing crack means that commonly employed simplified models (such V-shaped cuboid-shaped) have received testing. This study examines feasibility 3D by combining...
To investigate cyclic deformation behavior of natural soft marine clay-involved principal stress rotation, a series undrained tests were conducted by using GDS hollow cylinder apparatus. The rotates 5000 cycles while the deviator was kept at constant level. results show that tested samples are significantly dependent on ratio (CSR). Furthermore, different type generation axial strains occur under CSRs. With same CSR, strain is between considering and ignoring rotation. When CSR larger than =...

Many experimental data have illustrated that the strength envelops for soils are not linear. Nevertheless, linear Mohr–Coulomb (MC) parameters widely applied conventional method, software codes, and engineering standards in slope design practice.
