三峡船闸高边坡岩体开挖卸荷变形及流变分析

采用粘弹性理论和有限元法，对三峡船闸高边坡在施工开挖过程中岩体的蠕变变形以及应力、位移分布进行了计算分析。研究结果表明，边坡岩体由于开挖卸荷引起的蠕变变形大都量值不大，变形收敛的时间也较快，属于稳定性蠕变，不会引起边坡的失稳

Rheologic Deformation and Stability Analysison Rock Mass during Unloading Excavation Process forHigh Slope in Lock Area of Three Gorges ProjectDing

n the paper, the computation on creep deformation and distribution of stress-strain of rockmass in the excavation process for the lock high slope of the Three Gorges Project was conducted byusing the viscoelastic theory and finite element method (FEM). The results show that, most of creepdeformations caused by excavation for rock slope are quite small , and their convergence rate is veryrapid , so the rock mass creep will not influence the stability of the high slope.
