摘要
路堑高边坡已经成为了修建山区高等级公路中不可避免的一道技术难关，以炎汝高速公路建设工程为依托，对炎汝高速公路 LK141＋550～LK142＋205路段实地调查，选定了 LK141＋980处路堑高边坡作为数值模拟分析的研究对象，确定了5种不同的边坡支护方案。通过对 LK141＋980处路堑高边坡在采用5种支护方案进行 FLAC3D数值模拟，重点研究边坡的稳定性、位移和应力变化及分布规律并确定最佳防护方案，以指导实践。
High cutting slope has become an inevitable technical challenges in constructing high-grade highway.The thesis based on YanRu highway construction project and on the field investigation of Yan Ru Highway LK141 ＋550 ~LK142 ＋205 sections,I selected LK141 ＋980 cut high slope as the research object of this paper numerical simulation analysis,identified five different slope supporting plan. By LK141 ＋980 high cutting slope in the FLAC3D numerical simulation after five support scheme,key research of slope stability,the displacement and the stress variation and distribution,and determining the optimal protection scheme so as to guiding practice.
