| 摘 要： | 为了分析PFWD实测压力与弯沉之间的关系,现场选取了5种典型填料路基路段,通过改变落锤高度和承载板直径进行了大量测试,并与现场承载板法进行了对比.结果表明,在落锤高度改变而承载板直径不变的情况下,PFWD的压力和弯沉之间呈良好的线性关系,即路基表现为线弹性性质,且填料质量越好,路基模量越大,线弹性性质越明显；在承载板直...

| Abstract: | In order to analyze the relation between pressure and deflection measured with portable falling weight deflectometer(PFWD),the field subgrade sections of 5 typical fillers were selected,and many tests were carried out by changing the fall height and the plate diameter,and the test results were compared with that of the method of field bearing plate.The results show that(1) there are good linear relationships between pressure and deflection when changing the fall height and remaining the plate diameter,i.e.,... |
