| 双排桩扶壁挡土墙是高填土边坡的一种新型支挡结构,由于能较好控制边坡变形大和解决施工安全较差的问题而得到了推广应用.但是,这种支挡结构用于高填土边坡支护的设计计算较为复杂,且没有统一的计算方法,对指导设计带来一定的困难.文章根据高填土边坡双排桩扶壁挡土墙的受力特点,提出了一种基于模型试验和工程实测平面刚架模型的简便设计计算方法.将这种方法应用于某法院建筑填方高边坡治理方案设计,并对设计边坡的最危险工况利用有限元行了数值分析,模拟结果与设计方法计算结果吻合较好.边坡自施工开始进行了连续位移监测,竣工完成近一年半后水平位移最大值为21.3 mm.通过该工程实施结果表明,文章提出的设计计算方法方便可靠,对后续类似边坡工程设计具有一定的借鉴意义. |

| Double row piles buttress retaining wall is a new type of high fill slope retaining structure.due to the good control of the slope deformation and solving the problem of construction safety,it has been popularized and applied.But,at present,the calculation method of double row pile retaining wall design is comparatively complicated and there is no unified system,which brings some difficulties to the guidance design.According to the stress characteristics of high filling slope double row pile buttressed retaining wall,this paper proposes a calculation method of feasible design of model test and engineering test plane frame model,and applies this kind of design method in the high fill slope treatment engineering practice of a court building.In order to study the influence of the slope treatment plan on the environment and to improve the safety degree of the plan,the finite element software is used to analyze the most dangerous working condition of the slope,and the analytical results are compared with the calculation results of the design method.The results in the construction process and the slope displacement monitoring after the completion of the construction show that the design method is feasible.This method is simple and practical,and it has certain reference value for the similar slope engineering design. |
