软土中刚性桩抗弯试验研究

Bending Test of Rigid Piles in Soft Soil

通过对位于温州地区淤泥土质中的两个大直径刚性桩进行现场荷载试验,得到了弯剪共同作用下的刚性桩顶部弯矩与位移的关系曲线。相同条件下,试验得到的桩顶位移小于基于弹性地基理论的C值法计算的理论值。本文结果可为软土地基中抗弯钢桩的应用与推广提供参考。

Two large diameter rigid piles located in mud in Wenzhou were tested under field loads and the relationship curves of the bending moment and displacement of rigid piles under bending-shear interaction were obtained. Under the same conditions the measured displacements of rigid piles are less than the calculated data of C-value method based on elastic foundation theory. The results can provide reference for the application and popularization of bending steel piles in soft soil foundation.
