衡重式挡墙在山区高填方运用模拟研究

Simulation Study on Application of Weight Retaining Wall to High Fill in Mountainous Area

利用有限元分析软件,针对于山区坡地高填方工程中,利用衡重式挡墙进行支护的模拟分析,通过对墙后填筑接触面为水平和倾斜的两种情况模拟,对模拟结果中的支护结构衡重式挡墙的水平位移、竖直位移及高填方的沉降分析,得出结果:挡墙潜在的破坏形式存在差异,设计理念也需要做一定的调整,以保证整个工程的安全性与合理性;两种地形条件下的沉降位移结果计算结果表明两种变形特征存在差异;对于倒三角高填方的场地的规划需要根据沿着挡墙方向进行布置,从规划方面避免不均匀沉降的危害。

Based on the finite element analysis software,this paper simulates and analyses the support of weight retaining wall in high fill project in mountainous area.Two situations of horizontal and inclined contact surface of filling behind the wall are simulated,and horizontal displacement,vertical displacement and settlement of high fill are analyzed for weight retaining wall in simulated results.The result shows that the potential failure modes of retaining wall are different and the design concept needs to be adjusted to ensure the safety and rationality of whole project.The calculation results of settlement and displacement under two topographical conditions show that there are differences between two deformation characteristics.The site planning of high filling in inverted triangle needs to be arranged along the direction of retaining wall to avoid the hazard of uneven settlement in planning.
