摘    要:长三角地区很多城市处于长江漫滩地区,土体一般处于塑性状态,极易变形,地质条件很差.在这种情况下,如何合理选择支护设计及土方开挖施工方案,在安全、合理的前提下,做到既经济又保证工程进度,是一个值得探讨的问题.本文结合工程实例对软土地区基坑支护及土方开挖过程中出现的一些问题进行了初步的分析并得出一些有益的结论.

关 键 词:软土地区  基坑支护  土方开挖  问题与对策  长江  漫滩  区域  基坑支护  土方开挖  开挖施工  问题  对策  River  Land  Area  Flood  Supporting  Foundation  Pit  Excavation  Earth  Construction  Countermeasure  分析  开挖过程  软土地区

Abstract:Thereare some cites in Yangtse River Delta area situated in flood land area with its soil body in plastic state and easy to be deformed under such bad geological condition. The paper desribes how to choose a reasonable supporting design and earth excavation plan for garanteeing not only safety and reasonable, but also ecenomic construction , combined with enginening practice, some problems in foundation pit supporting and earth excavation process in soft soil area are analysed and a lot of beneficial results have been desribed in this paper.
Keywords:soft soil area  foundation pit supporting  earth excavation  problems and countermeasures
