水泥土桩压实系数特性的研究和运用

The Research and Application in Compaction Coefficient's Characters

水泥土桩桩身夯实质量是否合格,是根据土工试验压实系数来检定的,虽理论上要求压实系数≤1,但工程实践中有时会出现与该规定相矛盾的情况,使工程技术人员产生疑惑,并浪费了施工时间和增加了施工成本,本文通过试验数据和理论研究证明在特定情况下压实系数>1也是合理的,对其实际应用有着主要意义。

Whether the compaction quality of cement pile is qualified,it is according to the soil compaction coefficient to test. Compaction coefficient theoretically should be less than or equal to 1,but in practice sometimes compaction coefficient is greater than 1. That is contradictory to theory. The phenomenon often makes engineers puzzled,and wastes the construction time and increases the construction cost. Through the test data and theoretical research,the compaction coefficient greater than 1 is reasonable in certain circumstances. The research of the paper has very important practical significance.
