| 摘 要： | 针对当前既有重载铁路路基陷穴病害评价方法不足的问题,建立基于坍塌填塞法、坍塌平衡法、稳定系数法、普氏理论法的路基陷穴病害综合分析模型。通过工程算例对比分析各类方法的特点和适用条件,讨论各类方法的相容性和互斥性。研究结果表明:综合评价模型能够较好地避免单一方法的局限,获得客观、科学的评价结论。

| Abstract: | Aiming at the deficiency of the methods for evaluation of subgrade sinkhole defect in existing heavy haul railway,a comprehensive evaluation model for subgrade sinkhole defect is established based on methods of collapse plugging,collapse balance,stabilization coefficient and Pugh's theory.The comparative analysis of characteristics and applicable conditions of various methods are conducted with engineering examples.The consistence and mutual exclusivity of various methods is discussed.The results show that the limitation of single method can be avoided with the comprehensive evaluation model,and objective and scientific evaluation conclusions are obtained. |
