摘要
以结构可靠度理论为基础,采用概率极限状态设计原则,结合工程实例探讨了分项系数极限状态设计法在水闸设计中的应用。分析结果表明,在水闸设计中运用分项系数极限状态设计法有其优点,分项系数直接体现了设计中有关因素的变异性对结构可靠性的影响,使结构设计更趋于合理;但对有关分项系数还需进一步探讨,有关地基地质参数的标准值需进一步配套。
Based on structur al reliability theory,this artical uses the design principle of probability limi t state and combines with project practi ce to study application of partial safty factors limit state method in sluice de sign.The analysis results indicate that the partial safty factors can directly s how the effects of the relevant factor v ariabilities on the structural reliabity .Therefore,the method has superiority in sluice design and makes structural desi gn of sluice more reasonable.But some of the partial safty factors should be fur ther studied and standard values of corr esponding subgrade parameters need to be established to match.
