摘要
针对我国城市道路结合处暴露出来的易损害、寿命短等问题,对城市道路结合处不均匀沉降的原因进行了分析。从地基、路基、路面三个方面出发,提出了防治城市道路结合处损害的措施,即在保证结合处结构承载力的前提下,采用台阶开挖并铺设土格栅的方法,建立了路面结合处有限元法计算模型,并利用数值软件进行了分析,可为城市道路结合处的设计和施工提供有益的参考。
In allusion to the problem such as easy damage and short service life at urban road＇s junction, the reasons of the differential settlement of the junction was analysed. Base on the foundation, embankment and pavement of urban road, the measures to reduce the urban road＇s junction damage was put forward. In the case of guaranteeing bearing capacity of the junction structure, laying the geogrid was introduced. Using numerical analysis software, road＇s junction finite element method calculation model was established. The beneficial reference for design and construction of urban road＇s junction was provided.
