摘要
土坝填筑质量的优劣直接影响坝体的稳定和安全,对上坝土料碾压不实或不均匀,可能导致坝体局部沉陷、渗水、滑坡,甚至溃堤,采用三点击实法作为坝体填筑质量的检测方法,能快速确定填土的压实度和最优含水率与填土含水率的差值,从而保证土坝填筑质量和施工进度.
The filling quality of earth dam has a direct influence on the stability and safety of the dam body, while the une- ven rolling compaction on dam soil leads to the subsidence, seepage, landslip, and even inrush of the dam body. Three- point tamping method, as a kind of quality examining approach of dam filling, can quickly evaluate the filling compaction degree and the difference between the optional moisture content and filling water rate, ensuring the quality of dam filling and the construction progress.
