| 摘 要： | 针对既有铁路有砟隧道在重载、高密度列车荷载作用下产生的病害检测方法进行研究,对既有隧道病害检测方法进行适用性分析,认为高密度电法检测可用作有砟隧道混凝土垫层或仰拱病害检测,并进行现场试验验证。尽管这种无损检测方法有待于进一步论证和推广,但其研究为有砟隧道混凝土垫层及仰拱病害检测提供了新的思路,现场试验也论证了检测方法的可行性,可为既有铁路有砟隧道混凝土垫层或仰拱病害整治提供依据。 |
| 关 键 词： | 有砟隧道 高密度电法 混凝土垫层 翻浆冒泥 |

| Abstract: | This paper studied the disease detection methods of existing railway ballasted tunnel under the overload of high-density trains and analyzed the applicability of existing tunnel disease detection method,which concluded that high-density electrical method can be used to test the tunnel disease detection of ballasted tunnel concrete cushion or inverted arch and made the on-site experimental verification.Although the nondestructive testing method needs to be further demonstrated and promoted,its research provides a new idea for disease detection of ballasted tunnel concrete cushion and inverted arch and on-site testing demonstrated the feasibility of the approach,which can provide a basis for disease control of concrete cushion and inverted arch in existing railway ballasted tunnel. |
| Keywords: | Ballasted tunnel High-density resistivity method Concrete cushion Rising soil |
