摘要
针对路基填筑施工所在地区高地下水位的地形地貌、土壤地质等特殊条件进行分析,研究其基础土体含水量较高、孔隙比较大,透水性差,抗剪强度低,压缩性较高,具有流变性等特点容易引起后期路面质量问题,为保证工程的耐久性和运营安全性对路基填筑过程中质量控制进行分析。该文以“一带一路”东欧某地铁场平基建项目为工程背景进行研究,为类似工程施工质量控制提供理论支撑;针对场平路基填筑的施工质量控制应从多角度分析,科学选材,规范施工,提高施工作业水平,全方位把控施工质量。
Based on the analysis of the special conditions of topography,geomorphology and soil geology of high groundwater level in the area where roadbed filling construction is located,this paper studies the foundation soil with high water content,large porosity,poor water permeability,low shear strength and high compressibility.With rheological characteristics,it is easy to cause pavement quality problems in the later stage.Quality control in the process of roadbed filling is analyzed in order to ensure the durability and operational safety of the project.This paper takes the capital construction project of a subway section in"Belt and Road Initiative"in Eastern Europe as the engineering background to provide theoretical support for the construction quality control of similar projects,and the construction quality control of Changping roadbed filling should be analyzed from multiple angles and selected scientifically.Standardize the construction,improve the level of construction operations,and control the construction quality in all directions.
