Optimal row distance of retaining structure with double-row piles

  • 摘要: 运用有限元软件PLAXIS模拟并结合济南某双排桩支护深基坑的实际监测资料,对双排桩支护结构的最优排距进行了研究,并进一步分析了开挖过程中的支护变形和土压力。提出排距在2 D~4D(D为桩径)时支护效果最好,且根据模拟和监测结果进一步得出适当的桩排距应结合合理的施工方案,才能充分发挥双排桩控制变形的优势,降低工程造价。
    Abstract: Based on the numerical simulation by finite element calculation and the actual monitoring data for a large deep excavation in Jinan, the optimal row distance of retaining structure with double-row piles is studied. The deformation and earth pressure of the retaining structure during excavation are analyzed. The row distance of 2D~4D (D is the pile diameter) will result in the smallest deformation. Only appropriate row distance and reasonable construction plan can make full use of the deformation control.
