摘要
以某水电站为实例,结合数值模拟,研究了河谷下切过程中断层、错动带以及侧向剥蚀对地应力的影响情况分析,为坝址区地应力特征研究提供了科学依据。通过计算得出:在断层、断层与断层及断层与层间错动带交错部位岩体应力明显减小,而侧向剥蚀主要影响左岸应力分布,对右岸应力分布的影响不是很明显。
In certain hydropower plant as an example, combined with numerical simulation, this article studies the influence of the ground stress about the fault rupture, disturbed belt and lateral erosion during the valley incision, for the dam site area ground stress characteristic study provides scientific basis. Through the calculated: in the fault, fault and fault and fault and interlayer disturbed belt staggered site rock mass stress significantly reduced, and lateral erosion main influencing left bank stress distribution, the influence of the stress distribution of the right is not very obvious.
