摘　　要：利用生石灰与土之间的一系列复杂的物理化学反应,改善地基土的特性,进而提高地基土的承载力,减小地基沉降,从而满足实际工程的要求。但是目前复合地基沉降计算还不成熟,通过分析浅基础、桩基础和复合地基的区别,提出了比较简单实用的复合地基沉降计算方法,引入实际工程实例与分层总和法做对比来证明其实用性、合理性,同时也进一步证明了石灰搅拌桩作为一种可靠、经济的码头岸坡软弱地基加固方法,确实能起到减小地基沉降的作用。Due to a series of physical and chemical reactions between quicklime and soil, the characteristics of foundation soil can be improved, and thus the bearing capacity of foundation soil can be raised and settlement of foundation reduced. Through analyzing the difference among shallow foundation, pile foundation and composite foundation, this paper presents a simple & practical calculation method for settlement of composite foundation. At last, an engineering case was introduced to compare with stratified summation method to verify its practicability and reasonability. Meanwhile, it also proved that lime mixing pile can really reduce the foundation settlement as a reliable and economical consolidation method for soft foundation on dock′s bank slope.
