【摘要】 双鸭山市定国水库溢洪道施工图设计 ,采用衡重式挡土墙 ,利用减重台上填土增大挡土墙稳定性 ,使挡土墙工程量减少 ,地基应力均匀分布。在土质条件许可或冬季施工时 ,可根据设计挡土墙断面型式 ,最大程度放陡基坑开挖边坡 ,以节省土方开挖量。这样不但在设计上优化挡土墙断面 ,而且在施工中减少开挖和回填工程。最终达到降低工程造价 ,节约工期的目的。更多还原

【Abstract】 In design of spill way construction layout of Dingguo reservoir in Shuangyashan, adopting steady weight retaining wall, using weight reducing platfrom to fill soil in order to increase stability, reduce project cost, make foundation stress distribution uniform. And constructing, in allowable soil condition or in winter, you may base on design retainny wall section and make the foundation pit slope as best you can so as to reduce earth excavation. So not only optimzing design section but also reducing excavation and backfilling, at last reaching goal to reduce profit cost, economize on timelimit for a project.更多还原
