巴东长江公路大桥桥位边坡稳定可靠性研究

Research on the Reliability of the Bank Slope Stability of Badong Yangtze River Highway Bridge

以巴东长江公路大桥桥位边坡为例,在前人稳定性评价的基础上,建立了基于剩余推力法和Sarma法的边坡稳定可靠性分析模型,分析表明边坡系统可靠性指标(β,P,)能更准确地表达边坡稳定性、安全性和工程风险水平。

Taking an example of the study on the bank slop of Badong Yangtze River, an analytical model about reliability of slope stability is established with the residual pushing force method and the Sarma method. Previous stability assessments and analyses are taken for referential use. The results show that the reliability index (β,Pf) of bank slopes conveys stability, safety and engineering risk level more accuratly.
