厦门市东西溪防洪堤土方压实质量的控制

The quality control of soil compaction on flood control dike of the east and west rivers in Xiamen city

通过厦门市同安区东西溪工程防洪体系土堤和挡土墙背土料的碾压、振密试验,并进行现场跟踪检验,分析防洪土堤压实度、挡土墙后砂的相对密度与碾压遍数、振密机型、施工含水量的内在联系,为现场土方压实质量的控制找到一种较为有效的方法。

Through the roller compaction and vibratory compaction experiments on flood control soil dike of the east and west rivers in Tong′an of Xiamen city, the relationships between the compaction degree of flood control dike and the sand′s relative density at the back of retaining wall and the number of roller compaction, the type of vibratory compaction machine and the water content in construction were analyzed in this paper. An effective method for the quality control of soil roller compaction on the spot was found.
