安哥拉罗安达供水二期工程净水厂膨胀土地基处理浅析

An Analysis of Expansive Soil Foundation Treatment in the Rehabilitation of Water Supply System in Luanda,Angola(Phase Ⅱ)

在膨胀土地区修建构筑物,地基必须经过严格处理,否则易发生构筑物的基础外移、房屋开裂、地坪开裂等事故.结合安哥拉罗安达供水二期改造工程膨胀土的施工经验,阐述了膨胀土的性质,针对工程特点实施地基处理措施,选择了合理的基础结构形式,为膨胀土地区施工提供参考.

The foundation must be strictly dealt with while constructing buildings in expansive soil areas,otherwise,many accidents will occur,such as relocation of the building foundations,housing cracks,floor cracks and so on.Based on the construction experience of the expansive soil in the project named ＂ Rehabilitation of Water Supply System in Luanda,Angola（PhaseⅡ）＂,this article describes the nature of expansive soils,implements foundation treatment measures and selects a reasonable base for structures in light with the characteristics of this project,which will provide reference for the construction in expansive soil areas.
