Safety and Stability Analysis of High Slope of Railway Spoil Yard under Heavy Rain Condition
in this paper,the safety and stability of high slope of railway spoil yard under heavy rain is analyzed.By means of numerical simulation and limit equilibrium analysis,the influence mechanism of different rainfall intensity on shear strength,pore water pressure and slip surface formation of slope is discussed.The results show that the increase of groundwater level and pore water pressure caused by heavy rainfall is the main cause of slope instability,and the slope Factor of safety decreases significantly and the landslide risk increases significantly under high intensity rainfall.Based on this,the reasonable slope drainage design,reinforcement measures and ecological restoration plan are put forward to effectively mitigate the impact of heavy rainfall on slope stability.This study provides important theoretical support and practical guidance for railway engineering under similar geological conditions,and provides new ideas for engineering disaster-resistant design under extreme climate conditions in the future.
