| 摘 要： | 尾矿坝稳定与否是尾矿库能否安全的关键所在,尾矿坝又是随着生产过程而不断加高的特殊岩土工程体,各种因素处于动态变化过程中,这使得尾矿坝工程的不确定性尤为明显,工程难度较其他类型的边坡工程有增无减.运用FLAC模拟某尾矿坝的筑坝施工过程,分析了再筑坝过程中,逐级加载时上部荷载对原有尾矿坝体安全性能的影响,考虑了由下至上逐步...

| Abstract: | The stability of tailings dam is important to the safety of tailings pond.The tailings dam is a kind of particular geotechnical engineering body,which gets higher and higher with the course of construction and many factors are varying all the time,so the tailings dam is in a more dynamic situation,and the difficulty of building tailings dam is far larger than other kinds of slope engineering projects.This article modifies a process of building dams with the software-FLAC,analyzing the influence of load addition on the dam body that has been built.And the course of forming the gravity load is considered from the bottom step by step,superposition of all elements to get the ultimate force and deformation.So the article can provide a referential basis for building tailings dam,and decrease the possibility of tailings dam failure. |
