Stability Evaluation of Granite Residual Soil Slopes Using an Improved G1‐EWM Combined Weighting Cloud Model

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Granite residual soil (GRS) slopes are widely distributed in the humid and rainy regions around the world. Due to their unique mineral and pore composition, these soils exhibit a loose structure and are prone to softening and disintegration upon wetting.

Prediction of the Mechanical Response and Reliability Analysis of Support Structures for Deep Foundation Pits in Soft Soil Based on an Improved PSO–BP Neural Network

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Deep foundation pit support structures in soft soil are susceptible to deformation and instability under tidal action, making accurate prediction of their mechanical response and reliability assessment crucial for engineering safety. First, a three‐dimensional numerical model incorporating dynamic tidal loads was developed in ABAQUS to simulate the ...
