Shape of dynamic deflection basin of stiff - flexible bonding pavement subjected to dynamic load
刚柔复合路面结构弯沉盆形态分析
Dynamic modulus of layers is backcalulated by sidmod program with the deflection basin measured by fwd . static modulus is determined based on benkelman beam and plate bearing data . applicability of different devices in modulus calculation is summarized . the research results of this dissertation prorided the experimental and academic basis for the spread of fwd
用fwd测得的弯沉盆计算各结构层的动模量，用贝克曼梁和承载板测得的中心弯沉计算静模量，分析了不同设备与方法在进行模量反算时的适用性。
Imposing on the abundant fwd test data , a newly pavement intensity assessment standard is come into being . recurring to the program evercalc5 . 0 , the common rules of backcalculation modulus are introduced , moreover , the influence of instrument measurement error and input parameters are construed . utilizing the characteristics of deflection basin , so that it can assess the intensity of whole pavement structure
通过对丰富的fwd检测数据的分析，提出了全新的路面结构强度评定标准；借助evercalc反算程序，介绍了模量反算的一般规律，分析了仪器测量误差和输入参数对反算结果的影响，利用弯沉盆的几何特性对路面的整体强度进行评价，并建立了各结构层动模量与静模量间的相关关系。
