摘要:

越南某燃煤电厂选址在西南部海边滨海冲积平原,地勘资料揭示,厂址地基浅层存在厚度10.75~22.00m的淤泥和淤泥质黏土层,由于其分布广、强度低、变形大,严重影响电厂建筑物的结构安全。在电厂建设方案论证阶段,对软土层地基的预处理方案进行专题论证,并根据厂区不同部位承载力要求和施工进度不同,研究了软土层预处理施工方案。介绍了该电厂软土层地基预处理方案论证和施工方案研究过程,供同类问题处理时参考。

Abstract:

The site of a power plant in Vietnam was selected on southwestern coastal alluvial plain, based on the geological exploration report, there was 10.75 to 22.00m clay and silt clay exists in site shallow subgrade. This layer of clay is widespread, low intensity and high deformation, which seriously threatened the structural safety of power plant. During the construction plan discussion phase, soft clay foundation pretreatment plan was discussed based on the different bearing capacity requirements and different construction progress. This paper introduced the pretreatment plan and its discussion progress. Which could be referred for similar problem.
