城市道路设置地下综合管廊的路基沉降处理方法

The Subgrade Settlement Treatment Method for UrbanRoads with Underground Comprehensive Pipe Gallery

当地下综合管廊布置于道路机动车道下方时,道路与管廊地基处理方式及沉降控制要求不同,易导致机动车道纵向出现不均匀沉降,从而产生道路病害,缩短道路寿命,影响行车安全。为减少地下综合管廊建设导致道路不均匀沉降的问题,文章研究了广东省实际项目中的路基沉降及地下综合管廊沉降,根据不同的沉降特性,提出采取设置沉降过渡段的方式减少道路不均匀沉降,以供参考。

When the underground comprehensive pipe gallery is arranged under the road motorway,the foundation treatment methods and settlement control requirements of the road and pipe gallery are different,which can easily lead to uneven settlement in the longitudinal direction of the motorway,resulting in road diseases,shortening road life,and affecting driving safety.In order to reduce the uneven settlement of the road caused by the construction of the underground comprehensive pipe gallery,this paper studies the settlement of the subgrade and the settlement of the underground comprehensive pipe gallery in the actual project in Guangdong Province.According to different settlement characteristics,it is proposed to set up the settlement transition section to reduce uneven settlement of the roads for reference.
