摘要
运用三维线弹性有限元软件(3D σ)模拟了某深切河谷地应力场的形成演化过程,从而得到了研究区的现今地应力场,并对研究区地应力场的空间分布特征进行了分析和讨论,最后提出了地下厂房分析设计的地应力建议值,并对其岩爆可能性进行了评价。
Based on analysis of the geostress data measured in field, the evolution of the geostress field during the down-cutting of a deep-cutting gorge is simulated with three dimensional elastic finite method package, and the present geostress field is obtained. Then,the spatial distribution characteristics of the geostress field are analyzed and discussed in detail. At last, the in-situ stress values which used during the process of underground caverns analysis are suggested and the possibility of rock burst is analyzed,too.
