摘　　要：为合理制定公路边坡抗滑桩支护方案,采用有限元软件进行数值模拟分析。通过对比分析坡面位移、桩身位移和应力、边坡安全系数计算结果,认为支护后坡体和桩身的变形得到了有效控制,剪应力稳定在小范围内波动,边坡安全系数大幅提升,说明采用抗滑桩支护有效提高了边坡稳定性,支护方案具有可行性。Based on the semi Markov model,the detection data of asphalt pavement of ordinary highways in Jilin province from 2017 to 2022 are used.Firstly,the data is grouped for processing according to the highway grade and maintenance history to obtain the state transition probabilities of various pavement performance indexes under different grouping conditions.Then,the semi Markov state transition probability matrix library is obtained through the calculation.Finally,the pavement performance prediction equation based on the state transition probability matrix is established.The comparison results show that,the prediction model better characterizes the decay law of pavement performance and predicts the decay of pavement performance.
