重载铁路高填方路基施工技术

Construction Technology of High-Fill Roadbed of Heavy Haul Railway

针对重载铁路高填方路基施工技术研究,将以山西中南部铁路通道ZNTJ-20标重载铁路高填方路基填筑工程为案例,从工程概况分析入手,结合路基填料选择和填筑工艺试验,对路堤施工工艺及控制要点展开论述。最后,论文基于工后沉降观测结果,总结了重载铁路高填路堤的施工经验。

In view of construction technology of high-fill roadbed of heavy haul railway, taking the high-fill subgrade project of heavy haul railway in ZNTJ-20 section of the railway in south central of Shanxi, paper analyzes the project profile, combing with the selection of fill, and the filling process test, discusses the construction technology and control points of roadbed construction, finally, paper summerizes the specific experience of high-fill roadbed construction of heavy railway based on the observed result of post-construction settlement.
