囤船码头靠船桩现场测试及分析

Site Measurement and Investigation of Fender piles ofPontoon Wharfs

本文叙述万吨油轮靠泊囤船码头时,利用位移传感器多点同步测试靠船桩在水上和水下二部位的水平变位相橡胶护舷的压缩过程线。依据实测资料分析了作用在桩上的靠船力、桩的弹性曲线和有效吸能曲线;文中还分别用悬臂梁法和M法分析了桩的计算入土深度,最大弯矩和土的m值等,并与设计值作了比较。

A method for measuring the horizontal displacement of the fender piles over and under the water surface,and deflection curves of the rubber fenders simultaneously at the different points with the displacement transmitters when 10 00C-tonner-oil carrier berths at the pontoon wharf is described in this paper. According to the measured data, the berthing impacts which act on the fender piles, elastic curves and effective energy absorption curves of the piles are analysed. The depth of embedment, the maximum moment of the piles and the value of the coefficient of soil reaction 'M' are calculated by cantilever beam method and 'M' method respectively. The calculated results are also compared with the designed values.
