The compaction degree is an important index of the roadbed and the road surface.

压实度是路基和路面的一项重要指标。

The tests include compaction test, unconfined compression test, dynamic strength and dynamic strain test and so on.

包括击实试验、无侧限强度试验、动应变和动强度试验等。

The compaction effect of artificialIy drilled lime-soil pile is not obvious comparing testresults of soils between piles at different position. Furthermore the shear property of soils between pilesis studied.

通过对不同位置的检间土的物理力学性能的试验比较，表明人工成孔挤密灰土桩对桩周土的挤密效果不明显。

Ground compaction job is a important foundational project of earthwork construction water power engineering civil engineering and city planning engineering etc.

基础压实作业是土工建筑、水工建筑、道路工程、市政工程等建设中一项非常重要的基础性工程。

In the compaction process, the closer the soil water content is to the optimal water content, the stronger this correlation is. The correlated mining results are analysed with soil structure theory.

试验数据的相关性挖掘结果表明，击实率与湿陷性有较强的关联性，与湿陷系数为显著的负相关关系，击实过程中土的含水率越接近最优含水率，这种相关性越强；运用土的结构性理论对相关性挖掘结果进行了机理分析。

For solving the problems in the grouting fields, experimental study ,theoretical analysis and numerical simulation were used to study the grout diffusion of permeation, compaction and vibration grouting.

本文采用试验研究、理论分析和数值模拟相结合的方法,针对目前注浆领域存在的不足,对渗透、压密以及振动注浆浆液的扩散范围与理论进行了比较深入的研究。
