摘　　要：为了研究本地区海相软土地基采用水泥土搅拌桩进行加固技术,提高海相软土地基承载力的可行性.选取了本地区典型的海相软土场地,采用水泥土搅拌桩对软土地基进行加固,利用浅层平板载荷试验和复合地基载荷试验的方法,对海相软土加固前后的地基承载能力进行了比较分析.结果表明,利用水泥土搅拌桩对海相软土地基进行加固,可以有效地增强海相软土地基承载力.In order to study the feasibility of improving bearing capacity of marine soft soil foundation through the technique of reinforcing local marine soft soil foundation with cement-mixing piles, we select typical marine soft soil site and reinforce the soft soil foundation with cement-mixing piles. Through super- ficial plate loading test and composite foundation loading test, we conduct comparative analysis on the bear- ing capacities of marine soft soil foundation before and after the reinforcement. Results show that reinfor- cing marine soft soil foundation with cement-mixing piles can improve the bearing capacity effectively.
