摘要
采用近年来对断续节理岩体本构关系的研究成果,从岩体稳定性出发,考虑现场施工的约束条件,在每次开挖两个分块的前提下,对某大型节理岩体地下厂房洞室群施工顺序做了优化分析。发现优化方案比原有方案围岩稳定性有较大程度的提高,并得到一些有益结论。
In this Paper, on the basis of a new rockmass fracture damage model and in situ construction condition, and on the supposition that two sections are excavated in each step, the construction sequence majorization is performed for a group of carverns in Xiaolangdi water conservancy engineering.The stability of surrounding rockmass of majorized scheme is remarkably improved compared with that of original scheme and some useful results are obtained.
