新建铁路路基下埋藏墓穴坑洞的探查及其工程处理

路基的填方地段在铺轨初期加载列车运行震动后,往往会引起路堤原地面下埋藏墓穴等其它坑洞产生塌陷,是新建铁路运营初期的多发病害。针对集包三四线初期运营遇到的路堤基底塌陷问题,对设计文件、施工方法、工序、工艺进行逐一排查。采用综合勘察手段,经分析研究,提出了解决问题的对策,消除了行车安全的隐患,对同类线路病害的整治具有一定的借鉴作用。

Probation and Engineering Treatment on the Burial Tomb Pit Under the Embankment of Newly-Built Railway Lines

At the beginning of the track laying, the filling section of roadbed will shake when the train comes into operation so as to cause pit collapse like burial tomb under the original ground of the embankment, which constitutes frequent diseases at the early stage of the newly built railway operation. Aimed at the embankment base subsidence problems in the early operation of set package three or four line, investigations are made over design documents, construction method, process and crafts. Countermeasures have been taken to eliminate the safety hidden troubles with the comprehensive prospecting methods by exploration and analysis, which serves as a certain reference for similar lines.
