| 摘 要： | 随着铁路时速的不断提高,对于路基稳定性也提出了越来越高的要求。为了有效地控制软基地段路基的工后沉降和不均匀沉降,各种软基处理工法在铁路建设中得到了越来越广泛的应用。本文结合遂渝铁路的软土地基处理实例,详细地介绍了振冲碎石桩的成桩工艺,施工质量控制应注意事项,桩体及桩间土强度检测等。最后,对今后的施工和设计提出了一些建议。

| Abstract: | With the railway speed increasing, the requirement for the stability of the roadbed is made higher. In order to control the subside after construction and the uneven subside effectively,various techniques for reinforcing soft ground have been applied in the railroad project. Based on the example of reinforcing soft ground in Suining-Chongqing railway, this paper introduces the techniques of vibro-replacement gravel piles in details. And the important items of quality control and the intensity examination are also introduced. Finally,this paper put forward some proposals about construction and design. |
