摘要
Abstract
In order to study the influence of rainfall seepage on the seepage stability of the internal dump of Ha'erwusu Open-pit Mine,the single step of internal dump is constructed as a model,and the Morgenstern-Price method based on the limit equilibrium theory is applied to Geo-Studio software to calculate the minimum safety coefficients of the slopes under four working conditions with the same rainfall,and to evaluate the stability of the steps of the internal dump under this rainfall condition.The results show that the change of slope pore pressure under the four working conditions is significant,the change of slope safety stability coefficient in a short period of time is similar,the minimum safety coefficient meets the production safety specification,and there is no major production safety hazard.关键词
