| 摘 要： | 地下巷道上方的工程建设,需进行在地面荷载作用下工程建设场区稳定性和地面变形的评估。采用随机介质理论,根据地下巷道结构特征、支护条件和地质条件,将岩土体视为一种“随机介质”,将开挖岩土体引起的地表下沉视为一随机过程,对不同工况下地下巷道周围岩土体的应力及应变作了计算机模拟计算分析,进行定量计算评估,得出场区稳定性、地面最大沉降和倾斜度的定量评估结论。

| Abstract: | Under the ground-load effect the ground distortion and stability of engineering building estate above underground roadway are evaluated by the random medium theory.In the light of structural character,geologic and retaining conditions the rock mass is regarded as random medium and the ground subsidence in digging soil and rock as random course.As a result it is possible to simulate the stress and straining of soil and rock surrounding roadway in different engineering conditions and carry through ration assessment,resulting assessment conclusions of estate stability,the most gradient and ground subsidence. |
