刚性路面接缝传荷能力的评定与分析——FWD开发应用研究

Assessement of Load Transfer Across Joints in Rigid Pavements Using the FWD

本文以弹性薄板有限元分析为依据,以落锤式弯沉仪(FWD)为工具,对混凝土路面接缝的传力性能进行了理论分析,并应用FWD对室内混凝土试验路上多种传力杆布型下4条接缝的传力状况进行了实际评定.

Based on the finite clement method of the clastic thin plate, the load transfer capacity of jointed concrete pavements has been studied. For measuring the load transfer efficiency, a concrete pavement, consisting of six slabs, incorporated with each other by nonuniformly spaced dowel joints, was loaded and measured by the falling weight deflectometer (FWD) test system.
