坝体填筑所需碾压机具、铺土厚度及碾压遍数等碾压参数,是根据土料的物理、化学性质及其自然含水率通过碾压试验确定的,土料含水率和铺土厚度是坝体碾压质量控制的要点,而坝体与岸坡结合部的处理既是施工控制重点,又是施工难点,是施工的薄弱环节,若处理不当,将可能沿岸坡形成渗流通道,严重时会引起工程事故。
Rolling compaction equipment required for dam filling, pavement thickness and rolling time and other rolling parameters are based on the physical and chemical properties of soil material and its natural moisture content determined by the rolling test, soil moisture content and shop The thickness of the soil is the main point of quality control of the dam rolling. The combination of the dam body and the bank slope is not only the focus of construction control, but also the construction difficulty, which is the weak link of construction. If not properly handled, the seepage passage may form along the slope, Serious accidents can cause accidents.
