To address potential anti-sliding stability issues of mudstone fill materials in the stockyard of the Pinglu Canal project under various working conditions,this study conducts an in-depth investigation into the characteristics and anti-sliding stability of silty mudstone within the stockyard.Through in-situ direct shear tests and large-scale direct shear tests conducted in the laboratory.The Geostudio software was utilized for detailed calculations of the overall and slope anti-sliding stability of the stockyard under normal operation,continuous rainfall,and seismic conditions.Numerical simulations and analyses were performed using the MIDAS GTS NX software.The results,based on the optimized geotechnical parameters from the in-situ and large-scale direct shear tests,indicate that the stability of the stockyard under various conditions meets the relevant standards,ensuring the overall stability of the project.This study provides essential theoretical and practical references for the design,construction,and long-term stability of the stockyard.
