摘要
为了分析顺层岩质边坡弱面注浆效应,采用了基于拉格朗日差分法的数值分析模型对其进行模拟。由FLAC3D数值模拟结果可知,弱面注浆加固能够使应力在顺层岩质边坡岩体中得到均化,避免应力集中现象的发生,从而增强边坡的稳定性。
In order to analyze weak plane grouting effect of consequent bedding rock slope, it is simulated by numerical analysis model which is based on Lagrangian difference method. The FLAC3D numerical simulation results show that weak plane grouting can properly make stress distribution in consequent bedding rock slope mass more homogenized and the phenomenon of stress concentration is avoided, thence it strengthens the stability of the slope.
