在土石坝施工中，如何合理、有效地控制粘土心墙填筑质量是确保坝体填筑质量的关键。以往的施工中，主要以干密度为控制指标，这种控制方法不能很好反映土料压实性的变化，尤其对土料性质变化较大的土料控制缺乏合理性。近年来以压实度作为填筑质量控制指标的方法，已逐渐普及。 In earth dam construction, how to control the filling quality of clay core wall rationally and effectively is the key to ensure the quality of dam filling. In the past, the dry density was the main control index. This control method can not reflect the compaction of the soil well, especially the control of the soil material whose soil properties change greatly. In recent years, compaction as a method of filling quality control indicators, has gradually become popular.
