摘要
桩基础是海洋平台结构中一个很重要的组成部分,但在现有的平台结构系统可靠性分析中往往不考虑它的作用。本文根据海洋平台的工作特点分析了桩基结构本身的可靠性计算,探讨了如何考虑带有桩基结构的海洋平台整体安全评估的问题。通过对桩基结构可靠性分析及例题计算表明,在考虑桩基作用影响时得到的平台结构系统可靠性指标值和失效路径都可能有较明显的变化,这在实际工程计算时应给予注意。
The pile foundation is a very important component in offshore platform structures, but its effect currently is not considered in reliability analysis of platform. Based on the working environment and features of platform, this paper analyzes the reliability calculation of pile foundation itself and researches safety asaeasment of platform with pile foundation structure. Results of study and calculations of example show that if the effects of pile foundation is taken into account, the failure probability and failure path of the platform structure system will be changed obviously, which should be paid attention in practice.
