中文摘要：
用FLAC^310初步分析了地震荷载作用下空间不均匀性对地下岩体洞室位移特征的影响。分析结果表明，随埋深、地应力侧压系数的增加，地震荷载的空间不均匀性对洞室的影响呈减小趋势。深超过300m埋深情况下地震荷载的空间不均匀性对洞室的影响小于浅埋洞室，侧压系数λ〈1的情况下地震荷载的空间不均匀性对洞室的影响较侧压系数λ〉1明显。
英文摘要：
In order to discuss response of cavern under spatial inhomogeneous, indicate In the present paper, the influence of spatial inhomogeneous on the displacement characteristics of underground rock cavern under the effect of earthquake load is analyzed by finite - difference program FLAC . The results of primary analysis indicate that the influence of spatial inhomogeneous on rock cavern under the effect of earthquake load will decrease with the increasing of the depth and ground stresses side pressure coefficient ; When the depth is more than 300m the influence degree of spatial inhomogeneous on rock cavern under the effect of earthquake load is lower than that when the depth is shallow （ depth 〈 300m ） ; and influence of spatial inhomogeneous under the condition of side pressure coefficient 1 are significantly great than that of 1.
