| 摘 要： | 为确定高速公路动静弯沉之间的关系,获得与实际相符合的回归公式,通过总结国内外动静弯沉相关关系的研究成果,结合河南省典型公路动静弯沉之间的相关关系式,采用FWD取代贝克曼梁进行路基或者路面弯沉值测试,并通过试验段的对比试验建立简单的相关关系式,进行FWD弯沉试验所测动弯沉与贝克曼梁所测静弯沉之间的换算,同时对动静弯沉关系式进行敏感性分析和应用对比分析。结果表明:该法确定的动静弯沉回归公式更接近真实,变异系数接近1;与其他回归曲线相比,最终回归曲线最接近实测值,回归效果最好,更适合普遍应用。

| Abstract: | In order to determine the relationsh obtain the regression formula accords with the fact p between dynamic and static deflection of the highway,to the paper used FWD to replace the Backman Beam for roadbed or pavement deflection test. The paper also established simple relationship type by comparing the test section, analyzed and compared the sensitivity analysis and application. |
