| 摘 要： | 通过系统的数值仿真试验,研究了蚀变带厚度、地应力侧压系数这两个因素对地应力异常分布区的影响.采用正交与均匀试验设计方法,应用有限差分分析方法,对各种计算工况进行分析,得到了规律性的结果.最后以江边电站引水隧道实际工程为例,分析蚀变带附近的应力分布情况并进行了岩爆等级预测.得出了可以指导工程实践的结论.

| Abstract: | The inference of alteration zone thickness and side pressure coefficient to abnormal stress distribution was studied by systematic numerical simulation.Using the test design method of orthogonal and uniformity and applying the analysis method of finite difference method produced regular results.On the basis of the riverside hydropower station tunnel,the influences of the alteration zone to the distribution of ground stress and rockburst degrees were studied,and some useful conclusions were obtained. |
