摘要
针对田湾核电站2#常规岛软土深基坑支护工程的特定条件,采用深层搅拌水泥土墙和拉锚式排桩结合形成的组合支护模式进行基坑支护,并提出了组合支护模式结构计算的简化方法,在此基础上完成了深层搅拌和拉锚式排桩系统的设计。实践证明该设计是成功的。
According to the existing conditions of the conventional island No.2 in TNPP(Tianwan Nuclear Power Plant),a combined shoring pattern of CDM(Cement Deep Mixture) retaining wall and anchored castinsitu piles was applied to shore up the deep foundation pit in soft soil. A simplified method was formulated to calculate the structure of such combined pattern. On the basis of this method, the design of CDM and anchored piles was accomplished and the design was proved to be successful.
