对沥青路面结构采取维修措施(加铺沥青层),将直接影响其可靠度。利用蒙特卡罗模拟法(MCS)分析沥青路面结构可靠度,并对维修变量(加铺层厚度、抗压回弹模量)和响应值、可靠度进行回归分析,得到用于计算维修后路面结构可靠度的回归模型。通过与弹性层状体系理论计算结果的对比,验证了这种计算方法的有效性。研究结果可用于路面结构可靠度预测,对于网级路面管理中优化模型的研究和维修方案的制定具有重要意义。
Asphalt pavement structure to take maintenance measures (plus asphalt layer), will have a direct impact on its reliability. The reliability of asphalt pavement structure was analyzed by Monte Carlo simulation (MCS), and the regression analysis of maintenance variables (thickness of overlay, compressive resilience modulus) and response value and reliability were obtained. Regression model of structural reliability. By comparing with the theoretical calculation of elastic layered system, the validity of this method is verified. The research results can be used to predict the reliability of pavement structure, which is of great significance for the research of optimization model and the formulation of maintenance plan in the network level pavement management.
