铁路路基改良土填筑工艺与试验方法研究

Research on the Filling Technology and Test Method of Railway Subgrade Improved Soil

随着我国铁路建设项目的开展,路基改良土应用填筑越来越多,在大规模填筑改良土施工之前,需要通过现场试验获取改良土填筑工艺参数,以确保铁路路基的施工质量。本文结合试验段铁路路基改良土填筑的工艺性试验,介绍了路基改良土填筑的施工工艺流程与试验方法,获得了了改良土填筑最佳工艺参数组合,研究结果可为类似铁路路基改良土施工技术提供参考。

With the development of railway construction projects in China,more and more embankment improvement soil is used for filling. Before large-scale embankment improvement soil construction,it is necessary to obtain the technical parameters of embankment improvement soil through field tests to ensure the construction quality of railway embankment. This paper introduces the construction process and test method of improved subgrade soil filling in combination with the technology test of improved subgrade soil filling in the test section of railway,and obtains the optimal combination of technical parameters of improved subgrade soil filling.
