摘要
对拦灰坝土石混合料进行3种不同铺填厚度、3种不同加水量、5种振动碾压遍数组合的现场试验,通过测试碾压前后的颗粒组成,沉降量、变形模量、干湿密度等确定1组优化参数作为现场施工控制参数,并对试验结果进行了分析,提出了相应的处理措施和建议。
The roller-compaction tests on soil-stone mixtures with two kinds of different paved thicknesses, three kinds of added water amounts and five kinds of vibrant compaction times combinations, are carried out and discussed. In terms of testing before and after compaction particle constitution, dry and wet density, settlement and deformation modulus, a set of optimum parameters are gained as control parameters on field-construction. In addition, some corresponding measures and suggestions are proposed by analyzing the test results.
