软土地基沉井工程施工的探讨

Discuss the Construction for Sink Well in Soft Soil

沉井是软土地基中深基础施工方法之一,在工程用地与环境条件受到限制或埋深较大的地下构筑物工程中被广泛应用。为满足布置要求,沉井时常常碰到超越规范要求或者碰到施工工期不合理、施工场地有限的时候。本文通过规程规范及专业手册,结合多年来的工程实践,简述沉井工程在施工中的一些体会、心得及工程经验的积累,并介绍一个沉井结构成功的实例,供大家探讨并作为今后类似工程参考和借鉴。

Sink well is one of built method in deep foundation of soft groundwork, It is used widely in limited ground and limited environment or in deep burying construction. It is contacted with the things exceed criterions or some unspecific items in criterions or inconsequence construction time limit for a project or limited construction field in order to satisfied arrangement. Some experiences in construction of sink well states simply through rules and criterions and speciality handbooks combined with practices in many years. A successful example is provided for discussed and used for reference.
