弃渣场堆排方式对边坡可靠度影响研究
Influence of Filling Modes on Reliability of Slag Dump Slopes
摘要
Abstract
[Objective]The filling mode of a slag dump is one of the main factors affecting the safety and stability of its slope.This study aims to investigate the influence of filling modes on the reliability of slag dump slopes,thereby providing theoretical guidance for the design and construction of slag dumps.[Methods]Based on the theory of random fields,this study investigated methods for generating random models of slag dumps with different filling modes.First,by combining the Monte Carlo method and the strength reduction method,a calculation method for the reliability of slag dumps with different filling modes was established.Then,the influence of different parameters on the reliability of slag dumps was analyzed through the control variable method.Finally,the influence of different parameters was ranked using the grey relational analy-sis theory.[Results](1)The proposed method could simulate slag dumps with different materials in the forms of clump de-posit,horizontal layered deposit,vertical layered deposit,and inclined layered deposit.(2)For slag dumps with clump de-posit,the more uniform the material distribution,the lower the failure probability.(3)For layered slag dumps,when the in-clination angle of each layer was close to the internal friction angle of the material,the failure probability of the slope in-creased.The order of the influence of each parameter on the slope reliability,from greatest to least,was:rotation angle,ver-tical correlation distance,and horizontal correlation distance.[Conclusions]To enhance the stability of a slag dump,during the dumping process,efforts should be made to ensure that different types of materials are mixed evenly.If the slag is dumped in layers,the inclination angle of each layer should be designed to be somewhat different from the internal friction angle of the slag material.关键词
