摘　　要：为了确定拦沙坝坝料的填筑及碾压参数,进行了室内试验和现场碾压试验。通过室内试验,获得了细砂、反滤料、过渡料及堆石料的物理特性,现场碾压试验得到了不同坝料合理的加水量、碾压遍数和铺料厚度等参数,并对试验结果进行了分析。结果发现,随着洒水量和碾压遍数的增加,坝料的干密度增大,其存在最优值,施工的参数可由该最优值处确定,但也应当考虑施工的便利。提出了相应的质量控制措施和建议。In order to determine the filling and rolling parameters of the dam,the indoor test and the field rolling test are carried out. The physical properties of the filter material,the transition material and the rock-fill material are acquired through the indoor test. Meanwhile,the parameters such as the added water amount,the vibrant compaction and the paved thickness are obtained,and the test results are analyzed.Additionally,the corresponding quality control measures and recommendations are put forward,which can provide a reference for similar projects.
