摘要:

落锤式弯沉仪(FWD)是目前国际上最先进的路面弯沉检测设备,利用FWD检测弯沉盆数据能够反算路面结构层的模量,进而对路面状况作出评价.在分析了FWD与传统弯沉检测设备贝克曼梁相比所具有的优越性和二者的线性相关性的基础上,利用基于系统识别原理的模量反算软件SIDMOD,结合具体工程实际,探讨了通过FWD弯沉检测进行道路施工质量控制的应用技术.实践表明,在道路施工期间,FWD弯沉检测技术结合路面结构层模量反算理论能够真实地反映道路实际施工质量,识别施工质量存在问题或隐患的路段和结构层.

Abstract:

Drop weight deflection meter (FWD) is the most advanced pavement deflection detection equipment in the world, using FWD to detect deflection basin data can reverse calculate the modulus of the pavement structural layer, and then evaluate the pavement condition. Based on the analysis of the superiority of FWD compared with traditional deflection detection equipment Beckmann beam and the linear correlation between the two, the application technology of road construction quality control by FWD deflection detection is discussed by using SIDMOD, a modulus inverse software based on the principle of system identification, combined with specific engineering practice. Practice shows that during road construction, FWD deflection detection technology combined with the modulus inversion theory of pavement structural layer can truly reflect the actual construction quality of the road, and identify the road sections and structural layers with problems or hidden dangers in the construction quality.
