区域沉降对城市轨道交通建设的影响及应对措施

Influence of Regional Settlement on Construction of Urban Rail Transit and Countermeasures

随着社会的进步,轨道交通已成为现代城市的标志。在轨道交通建设的过程中,一旦穿越沉降带或者沉降漏斗区,势必会给城市轨道交通的建设以及运营造成一定程度的影响。通过对广州地铁具体建设工作进行实际的分析和总结,并且分别对高程误差公式设计过程、地区沉降高程贯通误差计算以及实际建设过程中受地区沉降的影响以及应对措施进行了说明,保证了轨道交通建设安全实施,值得推广应用。相关经验可为日后相似工程提供参考。

With the social progress, the rail transit has become a sign of modern city. In the construction process of rail transit, it certainly will cause a certain degree of influence on the construction and operation of urban rail transit once through the settlement zone or settlement funnel area. The article analyzes and summarizes the construction of metro in Guangzhou, and explains the influence of regional settlement and the countermeasures in the elevation error formula design process, regional settlement evaluation passing error calculation process and actual construction process in order to guarantee the safe implementation of rail transit construction, which is worth to popularize the application. The relative experience can be referred for the similar projects in the future.
