STUDY ON THE STABILITY ANALYSIS OF RESERVOIR WATER RISE AND FALL ON THE RIGHT BANK SLOPE OF MAOXIGOU RESERVOIR FOR WATER RELATED SLAG STORAGE
The study aims to evaluate the impact of water level rise and fall in the Maoxigou Reservoir on the stability of the right bank slope wading debris pile,and explore effective prevention and control measures.Through on-site investigation and geological analysis,detailed calculation models were established for the DJ2,DJ3,and DJ5 water related slag bodies in the 7 slag bodies on the right bank slope.Using the SlopeW module in Geo Studio soft-ware,different parameters of different reservoir water levels were used to simulate the safety factor changes of the slag body under two working conditions of reservoir water rise and fall,in order to predict its stability.The research results show that changes in reservoir water level have a significant impact on the stability of the slag body,espe-cially during the rapid decline stage,which significantly reduces the stability of the slag body.A comprehensive pre-vention and control plan was proposed for this,which includes leading edge support,graded slope grading,and load reduction by cutting.The effectiveness of the above measures was confirmed through actual water storage tests.The research results have certain reference value for the stability analysis of water related debris bodies and the selection of prevention and control measures in similar reservoir projects,and have guiding significance for ensuring the safe operation of Maoxigou Reservoir and reducing geological disaster risks.
