摘要
针对某水电站放空洞进水口高边坡存在倾倒和滑移拉裂或滑移致拉裂块体破坏的可能性问题,采用FLAC有限差分法技术和极限平衡法,分别从边坡的应力、变形、塑性区发展和块体稳定性方面综合评判了高边坡的整体稳定性,结果表明该边坡整体稳定性良好。
The high slope of emptying tunnel intake for a certain hydropower station is cliffy and fracture development,which is possible to crack and slide to crush under the sliding pressure.FLAC finite difference method and limit equilibrium method are applied to evaluate overall stability of high slope from the aspects of stress,deformation,plastic region development and mass stability.The result indicates that the overall stability of the slope is good.
