海相软淤地区某深基坑支护设计与分析

Design and Analysis of a Deep Foundation Pit Support in Marine Ooze Area

深基坑开挖是一项非常复杂的工程,尤其是在海相软淤土层中,土质条件极差,地下水极为丰富,合理的设计方案是保证基坑顺利实施的先决条件。以连云港某海相软淤基坑工程为对象,对深基坑及其围护结构选型进行了分析,总结了深基坑围护设计中关键的计算与验算内容。最后对比分析了设计计算结果与实际监测数据结果,证明了所采取的围护形式的有效性,可为以后类似工程提供一些借鉴。

The excavation of deep foundation pit is a very complicated engineering, especially the soil condition is soft and the groundwater is rich in marine ooze area. The reasonable design scheme is a prerequisite for the successful implementation of the foundation pit. In a foundation pit of marine ooze in Lianyungang as the object, the selection of deep excavation and retaining structure is analyzed, summarized the key calculation and checking the content design of retaining of deep foundation pit. Finally comparative analysis of the calculation results with the monitoring data show the effectiveness of the results, the envelope form, can provide some reference for future similar project.
