【摘要】 土工格栅堆石进占筑坝是利用土工格栅堆石与土工布袋装土代替传统的柳石进占体。利用该技术筑坝工艺简单、结构合理、施工进度快、安全性能好、工程造价低。菏泽市黄河河务局于 2 0 0 0年汛前首次在黄河下游用土工格栅堆石进占技术修筑了杨集险工上延 9～ 10号坝。在施工中技术人员根据施工边界条件变化 ,采用了合理的施工工艺和流程 ,收到了良好的效果。更多还原

【Abstract】 The rock-fill structure with soil engineering grills occupied progressively is to use rock filling with soil engineering grills and soils filled with geo-textile sacks instead of traditional body occupied progressively with willow stone. The structure has characteristics with simple technology, rational structure, quick construction tempo, good safe property and low cost of project. Yellow River Heze Bureau had built 9～10# dams extended above Yangji vulnerable spot using techniques of rock-fill occupation with soil engineering grills in the Lower Yellow River first before flood period in 2000. According to the variation of boundary conditions under the construction, the technical personnel adopted rational construction technology and technological process, and achieved good results.更多还原
