随着国家西部铁路网总体规划的实施及各地高速铁路建设需求的提出,各地铁路线的建设施工正如火如荼的进行着。然而,膨胀土这个一直是困扰各施工单位的老问题,却始终影响着铁路建设的质量和进度。如果处理不好,将对后期的铁路运行和保养造成很大的安全隐患和困难。本文将针对膨胀土的特性,结合实地情况,对铁路建设施工过程中有关膨胀土的施工工艺进行探讨,希望能给各建设单位提供参考和帮助。
With the implementation of the overall planning of the national western railway network and the demand for high-speed railway construction in various places, the construction and construction of railway lines in various regions are undergoing in full swing. However, expansive soil, which has always plagued the construction units, has always affected the quality and progress of railway construction. If not handled properly, it will cause great potential safety hazard and difficulty to the latter railway operation and maintenance. This article will address the characteristics of expansive soil, combined with the field situation, the construction process of the railway construction of expansive soil to discuss the construction, hoping to give all the construction units to provide reference and help.
