| 摘 要： | 在对泰赣高速公路K211段高边坡现场地质调研及对设计资料分析的基础上,根据预应力锚索结构中锚索框架梁和土体相互作用特征,引入接触单元并编制有限元程序ContFEM,将坡体和防护结构作为整体计算得到接触面(单元)水平位移、切向应力,坡脚抗滑桩挡墙推力及墙身水平位移,结合传统坡体稳定性分析及长期监测资料,最后对该高边坡防护工程效果做出后评价。

| Abstract: | Based on the in-situ survey of K211 high slope and its protective design data,a program of contact FEM is designed using contact element,considering the interaction characteristics of prestress anchoring cable-beam and soil.Then,the horizontal displacement and tangent stress of contact interface,thrust and horizontal displacement of anti-slide pile wall are calculated.Moreover,comparing to the traditional slices analysis method and the monitored displacement data,the effectiveness of protective structure is evaluated. |
