高速公路煤系土再利用回填方法探讨

Discussion on the Method of Reusing and Backfilling Coal-measure Soil in Expressway

目前针对煤系土的研究主要是从宏观层面开展,本文针对高速公路域内的煤系土回填利用问题,通过对高速公路路域内的煤系土土质进行调查与研究,较系统的梳理出有效利用煤系土资源的方法。通过对煤系土特性分析进行工程分类,提出了有效地对煤系土层回填利用需要建立先进行煤系土工程分类,再确定处理方式与方法,以及施工工艺及质量要求的全过程系统利用方法,从而达到最大程度有效利用煤系土资源及保护环境的目的。

At present,the research on coal-measure soil is mainly carried out from the macro level.This article aims at the problem of backfilling and utilization of coal-measure soil in the expressway area.By investigating and researching the coalmeasure soil in the expressway area,the effective utilization is systematically sorted out.The method of coal series soil resources.Through the engineering classification of coal-measure soil characteristics analysis,it is proposed that the effective backfill utilization of coal-measure soil requires the establishment of a systemic utilization of the whole process of coal-measure soil engineering classification,and then determine the treatment methods and methods,as well as the construction technology and quality requirements.Method,so as to achieve the maximum effective use of coal-measure soil resources and the purpose of protecting the environment.
