水泥混凝土道面可靠性设计指标计算方法
Calculation Method of Reliability Design Index of Cement Concrete Pavement
摘要
Abstract
Based on the calculation method of reliability design index of cement concrete pavement,the problems and shortcomings of the current calculation method are analyzed,and the improvement of the algorithm is proposed.The reliability index provided by engineering structure design standard in China is basically converted by safety factor,and the sub-coefficient is basically converted by safety factor or reliability index.There may be problems that the design results of different design conditions do not conform to the macro law of reliability,and the design results of different design indexes are inconsistent.The reason is that the calculation of reliability design index neglects the correlation between design variables.Taking the correlation between variables into consideration of the overall reliability of the project,the improved reliability index and the sub-coefficient calculation formula have better applicability.Applied to the cement concrete pavement engineering,the correlation between the variables is judged by the resistance property,and then the quantitative statistics of related coefficient value is carried out respectively,and finally the appropriate value of the reliability index is calculated by the improved algorithm.关键词
