滨海软土地质条件下较大型沉井设计与施工探讨

摘要

In this article, the author takes the sewage pumping station # 2 in Tai Zhou city as an example, introduces the des-ign and construction conditions of larger open caisson under the conditions of high underground water level, high compres-sion resistance, and heavy liquefied, and comprehensive analy-zes the characteristics and difficulties of engineering, compares with various sinking schemes of open caisson, takes into acco-unt and determines the final design and construction program from the aspects of complexity of construction, safe reliability, and operational management.%　　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。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，并确定了最终的设计及施工方案。
