摘要基于统一强度理论，推导出非均匀应力场的巷道围岩塑性区边界线方程式，可用于预测不同侧压系数时地下深埋隧洞的塑性区大小及形状。 - 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 condition of < 1 are significant larger than that of > 1 ; when < 1 , the displacements of measured points in cavern increase then decrease with the increasing incident angle of shear wave , while , when > 1 , the displacements decrease then increase with the increasing incident angle of shear wave , and the influence of incident angle on the displacements of measured points tends to decrease with the increasing in - situ stress side pressure coefficient
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< 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> 1时的情况；当侧压系数< 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> 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。 - Based on matlab system , a multi - layer back propagation neural network model was developed , in which the effects of the depth from surface to the tunnel axis , tunnel diameter , groundwater level , as well as the elastic modulus , shear strength , side pressure coefficient and unit weight of soil and the space between excavated wall and lining on the ground subsidence were considered
