摘要
以温州某边坡为研究对象,通过现场勘查和室内分析边坡岩土特征,共发现了3段不稳定斜坡;利用赤平投影法和极限平衡法,对边坡进行定性和定量的分析,结果表明:AB段边坡在不利情况下边坡表部土体仍能发生滑塌现象;CD段边坡中下部岩体容易发生楔形破坏及浅表层岩体剥落;DE段边坡中上部土体的滑坡及下部挡墙不能满足边坡的抗滑作用。
Taking a slope in Wenzhou as the research object, through the on-site exploration and indoor analysis of the slope rock and soil characteristics, a total of three unstable slopes were found;The method of stereographic projection and the limit equilibrium method were used to analyze the slope qualitatively and quantitatively. It is shown that the slope of the slope of the AB section can still be collapsed under the unfavorable conditions;the wedge-shaped failure and shallow surface rock exfoliation are prone to occur in the middle and lower part of the CD segment slope;the landslide and the lower retaining wall of the upper part of the DE section slope can not meet the anti-sliding effect of the slope.
