击实试验是土工试验项目中比较重要的一个试验项目,也是比较繁琐的一项试验,室内击实试验是模似工程现场夯实原理,利用标准化的击实方法和操作规程,对土样施加一定的冲击荷载使之压实,从而确定所需的最大干密度和最优含水率,作为选择填土密度、夯实次数等主要依据。在击实过程中,影响土的最优含水率和最大干密度因素较多,通过对这些影响因素的分析,提高土的击实效果,达到击实试验的目标的。
Compaction test is a more important test project in the geotechnical test project. It is also a relatively complicated test. The indoor compaction test is the compaction principle of the analogue project site. By using standardized compaction methods and operating procedures, the compaction test is applied to the soil samples Of the impact load to make it compacted, so as to determine the required maximum dry density and the optimal moisture content, as the choice of fill density, compaction times and other major basis. In the compaction process, the influence of soil optimum moisture content and maximum dry density factors are more, through the analysis of these factors, improve soil compaction effect, to achieve the goal of compaction test.
