不同试验方法弯沉检测结果的相关性及可靠性研究

随着我国高等级公路建设事业的发展,检测工作的重要性越来越为人们所认识。针对我国目前公路工程检测技术不足急需改进的现状,作者通过现场对比试验,对目前公路检测市场中常用的三种检测手段,在弯沉检测结果之间的相关性和可靠性进行研究;分析表明落锤式弯沉仪相比于贝克曼梁式弯沉仪和承载板,在弯沉检测结果的相关性以及检测结果的可靠性方面具有良好的优越性,从而为FWD检测技术在公路工程上的推广应用提供了坚实的技术基础。

Relativity and Reliability of Deflection Testing Results in Different Experimental Methods

With development of high - type highway building cause in our country, the importance of testing work is increasingly known to people. Aiming at current situations in dire need of improvement owing to poor technique for highway engineering testing at present in our country, the author makes research on relativity and reliability of deflection testing results in three sorts of testing means in common use. Researching results show the relativity and reliability of deflection testing results with drop hammer deflectometer have a good superiority as contrasted to ones with BenKelman Beam and Bearing Plate,which has provided a solid foundation for spread application of FWD testing technique in highway engineerings.
