【摘要】 以弧形钢闸门自重、静水压力、闸墩及护坡自重、闸墩基础与地基间的摩擦系数和基底粘着力等因素作为随机变量,探讨了弧形钢闸门抗滑稳定可靠性分析方法,建立了抗滑稳定极限状态方程。结合工程实例对弧形钢闸门抗滑稳定可靠性进行了定量分析,可靠性指标b为4.1688,失效概率Pf为6.717×10-5,并与传统的容许应力法作了比较。结果表明,该方法更科学、更合理、更具有实际意义。更多还原

【Abstract】 With the static water pressure, weights of piers and protecting slope, friction coefficient of pierfoundation on ground and base cohesion etc. as random variables, the analysis method of anti-sliding reliabilityand its equation in stable limit for steel radial gates are given. The anti-sliding reliability of a given steel radialgate is quantitatively analyzed, with the reliability guideline b = 4.1668, and the probability of invalidation Pfis 6.717Х10-5. It proves that this method is more scientific and reasonable, and with more practical meaning.更多还原
