摘　　要：通过台州市某基坑实例,研究了双排桩与止水帷幕复合支护的基坑围护中各排桩体的荷载分担系数变化规律,分析了双排桩在基坑开挖完成后的内力位移分布特点,并预测了基坑开挖所引起的地面沉降量和沉降范围,研究成果可为类似工程建设提供一定的参考依据。According to some foundation pit in Taizhou, the paper researches the law for the loading distributive coefficient changes of rows of piles in the foundation pit enclosure of the double-row pile and waterproof curtain, analyzes the features of the internal force distribution of the double-row pile after the foundation pit excavation, forecasts the ground settlement and settlement scopes caused by the foundation pit excava-tion, and indicates the study result provides some reference for similar engineering construction.

关 键 词：双排桩 基坑围护 分担系数 地面沉降量
