落锤式弯沉仪与贝克曼梁弯沉检测方法的相关性分析

Correlation of Falling Weight Deflectometer and Beckmann Beam Detection Method of Subgrade Deflection

依据JTG E60-2008公路路基路面现场测试规程,通过在丹东市东港农村公路海民线、土大线(一级路)上的对比检测试验,着重分析了落锤式弯沉仪与贝克曼梁弯沉检测方法的相关性。结果表明:在相同的测试条件下,落锤式弯沉仪和贝克曼梁检测的弯沉值有较好的相关性,其相关系数能达到0.95以上,进而拓宽落锤式弯沉仪的应用范围,提高检测自动化水平。

According to JTG E60-2008 Road Subgrade and Pavement On-site Test Regulations,the correlation of falling weight deflectometer and Beckmann beam detection method of subgrade deflection was studied experimentally on Haimin Road and Tuda Road(both are first grade roads) which were rural roads in Donggang of Dandong City.The result showed that,under the same test condition,they had good correlation with correlation coefficient up to more than 0.95.Therefore,falling weight deflectometer can be widely used so as ...
