摘要
以目前道路检测工程中常用的落锤式弯沉仪(FWD)为基础,从反算原理入手介绍了当前国内外较为流行的路面模量反算方法,并比较了各种方法的优缺点。同时从力学模型、数学方法以及数据误差等方面分析了基于FWD反算路面结构层模量的影响因素,并进一步指出了现行方法中存在的问题,为该问题的进一步研究打下基础。
Based on FWD in the highway engineering detection at present,back calculation method of pavement moduli is introduced from back calculation principle and advantages and disadvantages of all methods are compared.The influencing factors of back calculating pavement structural layer moduli based on FWD is analyzed through the aspects of mechanical model,mathematical methods and data error,etc.,and the problems appearing in the existing methods are put forward to the further study.
