论路基压实度与地基承载力的关系

The relation between degree of compaction of road base and base bearing capacity

概述了用干密度作为压实质量控制指标的机理。阐述了重视标准击实线对工程的指导 ,注意不均匀土质对路基压实的影响及现场检测压实度时标准干密度的确定方法 ,对弯沉值不符合设计要求的情况 ,提出了相应对策。

the mechanism of using dry density as control index of degree of compaction is concisely discussed. Combined with actual situation, the author pinpoints that valuing standard compaction line has significant instruction on project and that uneven soil has also great effect on degree of compaction of road base. And the author gives method of deciding standard dry density when in site checking degree of compaction. Finally combined with situation that deflection value can't meet design demands when checking and appraising some measures are given.
