前言要求在深水域中和具有险峻环境荷载的地点安置固定式海洋平台,必须考虑到很深的而且通常是很复杂的桩基系统。与此同时,需要建立能对这种系统作合理分析的方法。对基础的分析来说任何分析方法的主要目的是确定系统中沿每一桩的荷载和变形(分析中考虑了变截面桩)、土壤对桩 The foreword calls for the placement of fixed offshore platforms in deep waters and locations with precarious environmental loads, taking into account deep and often complex pile-based systems. At the same time, it is necessary to establish a method that can reasonably analyze such systems. For the basic analysis, the main purpose of any analysis method is to determine the load and deformation along each pile in the system (variable cross-section piles are taken into account in the analysis), and soil-to-piles.
