摘要
该文以某填土高边坡工程所采用的上部悬臂挡墙、下部双排桩锚索组合支护为例,探讨了该支护体系的优缺点、设计计算方法和施工要点,通过将支护结构分解为上部悬臂挡土墙和下部双排桩预应力锚索后,采取弹性支点法计算得到支护结构的内力及变形并据此进行设计。在施工中根据现场地层情况动态调整设计,工程实例证明该方法可靠可行,适用于变形控制要求较高的高填方的边坡支护,具有一定推广价值。
In this paper,taking the combined support of the upper cantilever retaining wall and the lower double row piles anchor cable in a high fill slope project as an example,the advantages and disadvantages、design calculation method and construction essentials of the support system are discussed. The internal force and deformation of the supporting structure are got by elastic fulcrum method after decomposing the supporting structure to upper cantilever retaining wall and lower double row pile anchor cable.According to it,the design is dynamically adjusted according to the stratum condition in the construction.The engineering example proves that the method is reliable and feasible. It is suitable for the slope support of high fill with high deformation control requirements,and it has certain popularization value.
