摘要
分析我国现行承载板试验检测土基回弹模量方法,针对该方法存在的问题,基于对不同等级道路柔性路面结构下土基应力与位移系统的计算分析,提出新的适用于不同等级道路现场承载板试验方法,为准确测定土基回弹模量提供依据。
This paper analyzes existing modulus of resilience of soil roadbed detecting method via tests for bearing plates in China,and proposes new test methods applicable to bearing plates on road sites of different levels aiming at problems existing in this method and based on computational analysis for stress and displacement systems of soil roadbed under flexible pavement structures of different level roads so as to provide a basis for accurate measurement of modulus of resilience of soil roadbed.
