摘要
本文通过理论分析,对FWD提出了计算土基回弹模量的近似公式;通过较多的承载板和FWD两种方法的定点对比试验,探讨了两种方法测定的土基回弹模量的相关关系。结果表明两者之间具有良好的相关关系。因此,可以使用FWD快速获得大量的土基回弹模量资料。
This paper puts forward an approximate formula of calculating subgrade re-silient modulus determined by FWD. Through extensive insitu comparative tests correlatingbearing plate to FWD method,the relationship between the modulus values determined bytwo methods respectively was analysed.It is shown that there is a fairly good regressive re-lation which can facilitate the field investigation of subgrade moduli by FWD of vast amount.The application of FWD is thus developed.
