摘　　要：对于悬臂式挡墙倾斜变形加固,目前常见的加固方法中多采用预应力锚固工程进行主动受力加固,而采用被动受力加固工程应用研究甚少,因此研究被动受力状态的新型锚拉组合结构具有重要实际意义。本文以陕西某景区悬臂式挡墙倾斜加固工程为例,在倾斜变形悬臂式挡墙背侧设置悬臂桩,将桩与挡墙立板由连系梁刚性连接,形成被动受力的锚拉组合结构,并对其加固机理和加固设计与施工细节进行分析。经工程实践应用检验,该被动受力的锚拉组合结构有效控制了倾斜挡墙变形发展,取得良好的加固效果,可为今后类似的悬臂式挡墙整体倾斜加固工程提供参考。For the reinforcement of cantilever retaining wall with inclined deformation,among the common reinforcement methodsat present,prestressed anchor engineering is mostly adopted to strengthen the cantilever retaining wall with active force,while the research on the application of passive force reinforcement engineering is very few.Therefore,it is of great practical significance to study a new type of anchor pull composite structure under passive force state.Taking the inclined reinforcement project of cantilever retaining wall in a scenic spot in Shaanxi Province as an example,in this paper,cantilever piles are set on the back side of the inclined deformed cantilever retaining wall,connecting the piles with the vertical plate of the retaining wall rigidly by a coupling beam,forming an anchor pull composite structure under passive force,and its reinforcement mechanism,reinforcement design and construction details are analyzed.The engineering practice shows that the passive anchor pull composite structure effectively controls the deformation development of the inclined retaining wall,and achieves good reinforcement effect,which can provide references for similar cantilever retaining wall overall inclined reinforcement projects in the future.
