摘　　要：以新疆乌鲁木齐市"世纪花苑"三期工程废弃人防地道为实例,在查明研究区浅埋洞室分布特征的基础上,结合现场及室内试验获取相关岩土体物理力学参数,利用快速拉格朗日差分分析程序FLAC研究浅埋洞室在拟建高层荷载作用下的稳定性及其破坏过程,通过系列模拟图,较真实地再现了洞室围岩变形破坏、尤其是塑性区发展变化过程。As an example of the 'SHI JI HUA YUAN' in Urumchi City as an example, aims to present mechanism for failure under effect of every factors and variability law, on the basis of the general knowledge of their distributions, we can carry out systematic researches on the stability of wall rock mass. The failure mechanism under the effect of every factors and the variability law are studied by means of FLAC numerical simulation by choosing typical geological model.
