水下工程耐压结构安全系数可靠性计算

摘要

根据水下工程结构承载的特点和影响安全系数的各主要静态因素的随机分布,对“应力和强度正态模式”中的可靠性安全系数公式进行简化,并针对水下工程典型舱段结构和基本安全系数进行可靠性计算,为实际工程结构确定性安全系数的制定提供了参考方法和依据.%According to load bearing characteristic and random distributions of main factors for underwater engineering pressure structure, the stress intension's normal mode of the reliability of safety coefficient is predigested in this paper. A reference method is offered to guide the formulation of the deterministic safety coefficient.
