浅谈土基回弹模量三种测试方法的相关性

On the correlativity of three test methods of rebound modulus of subgrade

介绍了土基回弹模量三种主要的测试方法,即静载贝克曼梁法、动载落锤式弯沉仪法和承载板法,并通过现场的测试结果分析了其相关性,结果表明:三种测试方法在相同的测试状况下,弯沉测定值之间都具有良好的相关性,在一定条件下可以相互换算。

The paper introduces three main test methods of the rebound modulus of the subgrade, that are the method of Benklenman beam, FWD （Falling Weight Deflectometer） and bearing plate, and analyzes the correlativity of the test results in field. The result shows that deflection detection value of the three methods have good correlativity in the same condition, and can be converted to each other.
