摘要
利用落锤式弯沉仪和贝克曼梁弯沉仪两种检测方法对比实验,对试验路段(武汉市幸福三路)每块板块以及各板块不同部位进行弯沉、基层取芯以及霹雳抗拉强度测试,分析两种检测方法的检测原理,对比实验步骤以及测试结果,分析两种检测方法相关性,提出如何利用两种方法所测弯沉值准确判断板底脱空。
In order to accurately determine whether the bottom of the cement concrete pavement panel is empty or not,and the emptying position,this paper compares the two testing methods of the drop hammer deflection meter and the Beckman beam deflection meter through the actual road,No.3 Xingfu Road,Wuhan City,and tests the road section.Each section and various sections of each section were subjected to deflection,primary core and tensile strength tests.The detection principles of the two detection methods were analyzed,and the experimental procedures and test results were compared.It was proposed how to use the two methods to measure the deflection values,and how to accurately determine the bottom of the board and the correlation between the two detection methods.
