西南地区多以高山、丘陵地貌为主,地质条件复杂,进行高等级公路建设时,施工中的深开挖、高填方不可避免,文章采用有限元程序PLAXIS对昆洛路K0+380～+720段边坡工程施工全过程进行数值模拟和仿真研究,对施工过程中产生的不可避免的土体失稳的情况提前采取支护措施,从而避免了实际施工中出现土体的坍塌现象,保证施工能够顺利进行,同时,也保证了施工人员的安全。
Southwest China is dominated by high mountains and hilly landforms with complex geological conditions. During the construction of high-grade highways, deep excavation and high fillings in construction are inevitable. In this paper, finite element program PLAXIS is used to test the K0 + 720 sections of slope construction process of the whole process of numerical simulation and simulation studies on the construction process of unavoidable soil instability in the case of support measures taken in advance to avoid the actual construction of soil collapse occurred to ensure that Construction can be carried out smoothly, but also ensure the safety of construction workers.
