土工击实试验主要是模拟施工现场的环境测试土压实性质。使用标准的土工击实试验设施冲击土料,保证土料达到充分的压实效果,并按照压实的效果,对土料的最大干密度和最佳含水量进行研究,获得精准的数据,给公路路基施工提供更加良好的数据基础。文章对土工击实试验当中出现的常见问题进行分析,以便提升土工击实试验工作的精准程度,提高公路路基建设品质。 Geotechnical compaction test is mainly to simulate the compaction of the environment test soil at the construction site. Using standard geotechnical compaction test facilities to impact the soil material, to ensure that the soil material to achieve full compaction effect, and in accordance with the compaction effect of soil material maximum dry density and optimum moisture content to obtain accurate data to Highway subgrade construction to provide a more good data foundation. The paper analyzes the common problems that occur in the soil compaction test in order to improve the precision of geotechnical compaction test and improve the quality of highway subgrade construction.
