土料因其级配和矿物成分不同,其压实特性也就不同。本文以大房郢水库筑坝土料施工参数选定为例,提出筑坝土料的填筑标准应经过充分的试验论证予以确定,碾压试验对填筑工艺拟定和质量控制都具有重要的指导作用。 Because of its grading and mineral composition of different materials, the compaction characteristics will be different. In this paper, taking the selection of construction parameters for dam construction of Dafangliu Reservoir as an example, it is suggested that the filling standard of dam material should be confirmed by sufficient experimental evidence. Rolling test is important for the formulation of flotation process and quality control Guidance.
