滨海软土地质条件下较大型沉井设计与施工探讨

本文以台州市滨海污水2#泵站工程为例,介绍了在高地下水位、高压缩性、重度液化地质条件下,较大型沉井的设计及施工情况。综合分析了工程特点及难点,对各种沉井下沉方案进行了比较。最终,从施工的难易程度、安全可靠性及运行管理方面等多方面综合考虑并确定了设计及施工方案。

Discuss the Larger Caisson Design and Construction under the Conditions of Coastal Soft Land

In this article, the author takes Binhai Sewage Pu- mping Station # 2 in Taizhou as an example, describes the design and constmction of the larger caisson under the cond- itions of the high water table, high compression resistance, and geological severe liquefaction. Comprehensive analysis of the characteristics and difficulties of the engineering, and comp- ares with various Sinking schemes, takes into account and det- ermine the final design and construction program from the asp- ects of construction, security, reliability, and operational mana- gement.
