摘　　要：对芜湖某住宅小区地下人防工程的异型基坑围护进行了工程设计研究。该地下人防工程的基坑平面形状复杂,基坑边缘折转角多处为阳角,地上建筑物与基坑边缘距离近,建筑物边缘距基坑边缘净距的最小距离为4.50 m。针对这些条件,采用了水泥搅拌桩挡墙,结合门式钻孔灌注桩进行局部加固的基坑围护结构设计方案,有效解决了工程设计中的问题,可应用于工程实践。The design of unique pit exterior-protected construction on underground civil air defense in Wuhu city was introduced. The plane form of the pit was complex owing to many external comers. The distance between the building and the edge of pit is short, and the nearest one is only 4.50 m. To solve this disadvantage above mentioned, cement-soil walls and portal filling piles were used. This design efficiently solved the problem in EDP and could be used in engineering.
