基于离散元法的顺层岩质边坡的地震响应分析
Analysis of seismic responses of bedding rock slope based on DEM
摘要
Abstract
The seismic responses and anchor reinforcement effects of a bedding stereoplasm rock slope with multiple structural planes behind the powerhouse of a hydro-power plant by use of the DEM,and a optimal layout plan of the anchors is proposed.The research shows that displacements of the unreinforced bedding stereoplasm slope under seismic action is present the stepped increases,and the rock blocks fall at the end of earthquake.Displacements of reinforced slope diminish significantly,and the slope can remain stable in the earthquake.The shear force response of the anchor elements shows good agreement with the relative displacement response of the lay of terrain around the anchor element,which means that the relative displacement of the lay of terrain around the anchor is the main stimulation factor of the anchor reinforcement effects in the earthquake and the relative displacement of the lay of terrain emerging on slope surface and at a lower elevation is larger so that the shear force of the corresponding anchor is larger.Hereby this paper put forward the reasonable arrangement schemes of the anchor.关键词
