弯沉值与回弹模量对路基评定的应用

The Application of Deflection Value and the Rebound Modulus to the Subgrade Assessment

在对绵阳市九岭至花荄二级公路新建工程K6＋200～400路基的强度进行检测评定时，分别采用承载板法测量土基回弹模量和贝克曼梁法检测弯沉。通过这两种方法的实际检测数据的分析，最终对该段路基强度进行了评价。

This article carries on the detection evaluation from spend nine ridge Huagai secondary highway construction project K6＋200~400 of subgrade strength in Mianyang city, and adopts the bearing plate method to measure the soil base resilience modulus and Beckman beam deflection method detection. Through the analysis of these two methods actual testing data, the author final y evaluates the subgrade strength.
