| 摘 要： | 文章对珠江三角洲地区软土工程地质性质进行了研究。结果表明:该地区软土物质成分主要为水族矿物,具有较大的界限含水量,且其微观结构多为絮状链接结构或粒状链接结构,同时还具有土层厚度大,含水量高,灵敏度高,孔隙比、压缩性大,抗剪强度、承载力低等特性。针对该地软土的这一性质,综合比较几种地基加固方法,提出了采用排水固结法来进行软基处理。文中对排水固结法的原理及地基沉降的计算作了简要介绍,以便为实际工程提供一定的理论依据。

| Abstract: | During the period of engineering construction in Pearl River Delta,treatment of soft groundsill is always one of the most troublesome problems.Soft groundsill often looks like fluid.Large thickness,high compressibility,low bearing capacity,low anti-smooth stability,large sedimentation and long time for concretion are all its characteristics.As one of the basic treatment means for soft groundsill,drainage concretion method is efficient and most economical in treating deep thick silage. |
