基于双后轴的贝克曼梁法测试路基回弹弯沉的可行性研究

Feasibility Study on Using the Benkelman Beam Test Method for Roadbed Rebound Deflection Based on a Double Rear-Axle Vehicle

以浙江省嘉善县某道路6%灰土路基为对象,对基于双后轴车的贝克曼梁测试方法的可行性及双后轴车与单后轴车在测试结果上的相关性进行了研究。从可行性和相关性两个方面进行了论述,提出了基于双后轴车的贝克曼梁测试及修正方法,从而解决了工程现场无单后轴检测车的难题。

Based on the 6%gray soil subgrade in Jiashan County,Zhejiang Province,the feasibility of the Benkelman beam test method based on a double rear-axle vehicle and the correlation between the test results of double and single rear-axle vehicles were studied.The feasibility and correlation were discussed,and a Benkelman beam test and correction method based on double rear-axle vehicles was proposed to solve the problem of the lack of single rear-axle testing vehicles on the construction site.
