The results showed that the displacement of the surrounding rock of cavern evidently decreases with the increase of in-situ stress side pressure coefficient, as well as the decreasing rate of surrounding rock displacement of cavern with increasing at the

分析结果表明，地震荷载作用下，硐室位移随地应力侧压系数的增加明显减小，地应力侧压系数λ<1时的硐室位移量值随侧压系数的变化幅度明显大于地应力侧压系数λ>1时的情况；当侧压系数λ<1，随剪切波入射角的变化，硐室测量点位移响应先增加后减小；而当侧压系数λ>1，随剪切波入射角的增加，硐室测点位移先减小后增加，同时随地应力侧压系数的增加有减小的趋势。
