摘　　要：深基坑开挖支护是基坑施工的重点,尤其是在建筑密集、地下水位高、厚软土地区的深基坑支护,更是工程界关注的难题。主要讨论以考虑桩土共同工作的悬臂式双排桩支护体系和桩-预应力竖向锚索支护体系为基础的悬臂双排桩深基坑支护新体系,详细分析了支护新体系的受力机理,以及在工程应用中的工作原理。The support structure during the excavating of deep foundation pit is difficult, especially in the dense buildings, high groundwater level and thick soft soil area. In the article, the new system with double cantilever piles to support deep foundation pit is discussed, and the new system includes double cantilever piles cooperated by pile, soil and the pile and vertical prestressed anchor. Force mechanics and operating principle of the new support system are analyzed.
