摘要
对于交通量日益增大的高速公路,可以通过增设传力杆来提高路面缩缝的传荷能力,有效地减少错台和断板现象。提出了传力杆的合理布置方式,并通过现场试验和数值模拟进行了分析和验证。试验和数值分析的结果表明,本研究的结论是可靠的。
In order to improve the load transfer ability of the highway with heavy traffic, a dowel bar can be installed in the contraction joint of the rigid pavement. A rational method of disposal for a the dowel bar is proposed through test-in-place and finite element analysis. From the measured data and the finite element analysis, it is suggested that the conclusion could be reasonable.
