| 中文摘要:结合苏州某超高层建筑围护结构设计的工程实例，对围护桩配筋进行优化，并对沿周边非均匀配筋和均匀配筋进行强度、刚度和经济比较，同时对围护桩不同长度下基坑受力变形特征进行了研究。结果表明：围护桩采用不均匀配筋及长短交错布置，在受力性能上变化不大，但是能够降低工程造价，缩短工期，获得最佳的经济效益和社会效益。 |

| Abstract:Combined with the engineering case of the retaining structure design of a super high-rise building in Suzhou, the reinforcement steel was optimized; comparison was made on the strength, stiffness and economic of surrounding non-uniform reinforcement and uniform reinforcement; and study was made on the stress deformation characteristics of foundation pit under the condition of retaining piles with different length. The results show that there is little change in mechanical behavior when non-uniform reinforcement steel and retaining pile with different length are adopted, but low project cost, short construction period and the best economic and social benefits can be achieved. |
