摘要:
近海石油平台的桩基设计与施工中,国际上业已广泛应用波动方程分析。本文将一维波动方程的史密斯差分解应用于华北渤海油田的两根开口打入的原型钢管试桩(外径900毫米,变壁厚、桩长分别为69及72米)。计算结果与现场实测值(包括以后所进行的静荷载试验)相比甚为符合。本文还探讨了计算所用的一些参数变化时对分析结果的影响。
Abstract:
Wave equation analyses have, been widely used in the design and construction of pile foundation of offshore platforms in many countries. In this paper, Smith’s finite difference solution of one-dimensional wave equation is applied to two prototype steel pipe testpiles (900 mm o. d. with variable wall thickness and lengths of 69 and 72 m) which were driven with open ends in the Bohai oil field of North China. Calculated results agree reasonably well with field measurements (including the static load test performed later) and the influence of variation of some of the parameters on the calculated results is also studied.
