【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。更多还原

【Abstract】 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.更多还原
