问题的提出含砾类土填料的压实度检测是实际公路工程施工常遇到的难题。在实际施工中,按填土路基控制质量的填料中含有大量粒径大于2mm的砂、砾,在用常规击实方法得出的标准干密度检测压实度时,由于填料的均匀性很难控制,标准干密度无法全面代表现场施工的标准干密度,所以检测的压实度离散性很大,不能准确评价土基的压实度质量。
The problem of compaction soil gravel packing detection is often encountered in practical road construction problems. In the actual construction, according to the filling quality control subgrade filled with a large number of sand larger than 2mm, gravel, compacted by the conventional compaction method to determine the standard density of compaction, due to the uniformity of the filler is difficult Control and standard dry density can not fully represent the standard dry density of on-site construction. Therefore, the compactness of the test is very discrete and can not accurately evaluate the compaction quality of the soil foundation.
