| 摘 要： | 由于水泥路面板底脱空具有隐蔽、不易判别的特点,227省道吴江段养护改善工程分别采用了落锤式弯沉仪、多级荷载回归法与地质雷达等方法,并结合实际取芯,对水泥路面板底脱空进行现场验证与分析,得出了各种评价方法的适用性,为其他类似工程提供参考.

| Abstract: | Based on the fact that void beneath cement concrete slab is not so easy to identify,deflection and multi-stage loading of falling weight deflectometer as well as ground penetrating radar are tested on the Wujiang 227 provincial road improvement project.Applicability of various evaluation methods drawn from the abovementioned tests could be reference to other similar projects. |
