摘要
随着相关技术的进步,城市市政管网工程需新建或改扩建,其中沉井所起的功效不容忽视。然而,沉井深度与其规模密切相关,大型沉井施工中经常会遇到一些问题,如地下水位下降或周围土体下降,甚至导致地面凹陷。因此,以大型沉井施工中常见问题作为研究对象,通过调查、探究与分析,提出应对措施,以此为施工工程提供参照。
With the progress of related technologies,urban municipal pipe network engineering needs to be built or modified.The efficiency of the caisson can not be ignored. However,the depth of open caisson is closely related to its scale. There are often some problems encountered in large open caisson construction,such as the decline of groundwater level or the decrease of surrounding soil,which leads to surface depression. Therefore,taking the common problems in large open caisson construction as the research object,the countermeasures are put forward through investigation,exploration and analysis,so as to provide references for construction projects.
