摘要
采用两步反演分析的方法,得到反映围岩综合性状的弹性模量E、水平地应力P和粘性参数η的值,通过仿真分析验算反演参数的合理性并对围岩性状和支护结构予以评价。结果表明,文中所用方法对大型洞室施工期的稳定性状可做出及时、准确的判断,具有较好的适用性。
The article applied the method of two-step back analysis, the value of E（Young＇s modulus）, P（horizontal ground stress） and η（viscous parameter） can be obtained, which can be used to reflect the synthetical character of rock mass. Finally the rationality of inversion parameters could be verified and the security of rock mass and support structure could be valuated. To sum up, the method of the article could make timely and accurate estimation on the stability of large underground cavern during construction, and was very applicable.
