| 摘 要： | 煤岩体风化后强度明显降低,尤其火烧区煤岩风化后遇水软弱极易发生崩解,且在不同含水率状态下煤岩抗剪强度差异很大,严重威胁到边坡工程的安全及稳定。针对别斯库都克露天矿火烧区露头煤岩风化严重的情况,对火烧区露头风化煤岩进行标准固结实验、崩解试验和不同含水率条件下的剪切实验,得到火烧区露头风化煤、岩的崩解状况,找出软弱土岩的粘聚力与内摩擦角随含水量的变化规律,研究结果对边坡工程稳定性分析和评价至关重要。

| Abstract: | The intensity of coal rock decreases significantly after weathering,especially the burning area coal rock weathering and water weakness can happen disintegrating easily,and the shear strength of coal rock in the state of different moisture are very different,serious threat to the security and stability of slope engineering.According to Biesikuduke open-pit mine fire coal rock outcrop weathering serious condition,the burning area weathered coal rock outcrop standard consolidation test,disintegration test and different moisture content conditions shear experiment,get burning area outcrop weathering coal and rock disintegration situation,find out the rule of weak cohesion and internal friction angle of soil and rock with variation of water content,the results is very important to slope stability analysis and evaluation. |
