既有铁路路基K_(30)和E_(v2)检测辅助装置及方法

Auxiliary devices and methods of K_(30) and E_(v2) tests on existing railway embankment

针对既有线路基检测中进行K30和Ev2试验困难的问题,设计了一套有效的反力装置及试验台,解决了在路堤边坡上进行K30和Ev2试验的反力问题及在边坡斜面上安放仪器设备困难的问题。将该设备和检测方法运用于朔黄重载铁路路基检测工程实践,结果表明,试验效果良好,有借鉴和推广价值。

In order to carry out K30and Ev2 tests for existing railway,an effective set of counter-force device and test bed have been proposed in this paper,which can provide not only adequate counter-force for K30and Ev2 tests,but also convenience for equipment installation on the slope.The new equipment and corresponding test method have been applied to the railroad bed detection for Shuo-Huang Heavy Haul Railway effectively.The equipment and method.can also be applied to the similar tests
