粉质土压实性能的试验研究

试验研究发现，粘质粉土的标准击实曲线呈双峰特性，压实性能较差，压实后的干密度和压实系数很难达到设计要求．故不宜作为填方工程的土料。通过标准击实试验、静力压实试验，系统地研究粉质土的动、静力学击实性能，明确粉质土的工程特性．并最终得出粉质土的静压力和压实的难易程度与颗粒级配以及液限等物理量之间的变化规律。

Compaction Characteristics Experiment Study of Silt Soil

Experiment results show that the compaction curves of silt soil will has two peak values and the compaction property is not satisfying. Dry density and compaction factor of compacted fill cannot satisfy the engineering. These soils are not suitable for fill materials. A series of tests have been carried out, such as standard compaction test, static compaction test so as to analyze static and dynamic mechanics characteristics systemically and get to know the engineering property of silt soil. The relationshi...
