城区泵闸工程的特殊基坑设计与应用

Design and Application of Special Foundation Pit in Pump Gate Project of City Area

位于市区的泵闸工程受到场地条件限制和周边环境保护需要等因素影响,基坑设计难度较大,由于工程主体结构坐落于河道上,导致泵闸工程的围护结构不同于传统基坑工程。针对此类特殊基坑特点和难点进行分析,提出了相应基坑设计策略,并结合工程实例的成功应用经验,为类似工程的基坑设计和施工提供参考。

The pump gate project located in city area is influenced by the restriction of field condition and protection demand of surrounding environment. The design difficulty of its foundation pit is great. The main structure of the project located on river leads to the building envelope of the pump gate project different from the conventional foundation pit project. Aiming at this issue, the article analyzes the characteristic and difficulty of foundation pit, and puts forward the relative design strategy of foundation pit. The successful application experience of engineering cases can be referred for the design and construction of the similar foundation pits.
