Abstract

Abstract: Grouting treatment is an effective method for treatment． In order to reveal the effect principle of bolt-grouting body to slope fixation，strength reduction of Finite Element Method ( FEM) has been used． Through this method，the deformation of bolt-grouting body and the stability coefficient of slope have been calculated． The results show that putting the bolt-grouting body into the slope can improve the stability of slope，and setting the bolt-grouting body vertically is better than setting it horizontally; the best position of bolt-grouting body is at about 1 /3 height of the slope; the influence of the angel between bolt-grouting body and slope to slope fixation effect is significant．

Key words: bolt-grouting body, slope fixation, Finite Element Method( FEM), strength reduction

摘要： 为揭示灌浆锚固体对固坡效果的影响规律,利用有限元强度折减法,计算了单根锚固体分别在垂直或水平布设于坡体不同位置条件下以及布设角度不同等条件下锚固体的变形和边坡的稳定系数。分析表明: 在坡体中置入锚固体对边坡的稳定性均有不同程度的提高,其中垂直布设较水平布设的固坡效果更为显著；布设位置在坡高约 1 /3 处最为理想；锚固体与坡面夹角也对固坡效果有较大的影响。
