Application of retaining structure with double-row piles in a hydraulic excavation

  • 摘要: 某水闸基坑采用双排桩支护,通过支护结构的内力、位移分析计算对MIDAS/GTS程序和理正双排桩程序进行了对比,在计算模型基本相同的情况下计算结果有较好的一致性;采用理正双排桩程序对基坑支护断面的内力、位移及前后排桩不同土压力分担系数进行了比较分析,并对分担系数影响支护结构的内力、位移的原因进行了分析;最后对支护结构的位移进行了严密的监测,对双排桩的位移特性有了初步了解,对双排桩支护设计有较好的参考价值。
    Abstract: The retaining structure with double-row piles is used in an excavation of sluice. The internal force and displacement of the retaining structure with double-row piles are compared with those of MIDAS/GTS and double-row pile program of Lizheng. In the case of the same computational model, the calculated results are in good agreement. The sectional drawings of the retaining structure with double-row piles are analyzed from the internal force, displacement and different sharing ratios of lateral earth pressures on front-and rear-row piles. Finally, it provides certain reference value in designing the retaining structure with double-row piles. The displacement characteristics of double-row piles are preliminarily understood, by monitoring the displacement of the retaining structure with double-row piles.
