| 摘 要： | 通过旧路加宽室内模型试验可以获得新旧路基间的变形和刚度差异,以及经过加筋处治的路基内压力分布特点,且室内疲劳加载试验可以较有效地测试路面结构内的应力应变状态。试验结果可以用来验证旧路加宽综合处治技术的有效性和可靠性,并可对理论分析结果进行验证。

| Abstract: | The uneven deformation and rigidity, and the pressure distributing characteristics of the roadbed are acquired by the model test indoor for widening of the old road. The stress and strain conditions of the pavement structure are gauged availably by the indoor test of fatigue loading. The test results can be used to verify the validity and reliability of synthetical disposal technology for widening of the old road and to confirm the results of theoretical analysis. |
