摘　　要：随着国家对环保的日益重视,中粗砂等优质填料的价格也快速上涨,致使许多陆域回填工程的成本大幅增加。针对回填中粗砂紧缺、价格高的问题,进行工程弃土的陆域回填再利用技术研究,采用室内试验及现场试验的方法,分析工程弃土的工程性质、环保特性及工程弃土环保填埋后的利用效果。结果表明,工程弃土代替中粗砂进行回填技术可行,满足环保要求且经济社会效益显著。With the increasing attention of the country to environmental protection,the price of medium-coarse sand and other high-quality fillers have also risen rapidly,resulting in a large increase in the cost of many land backfill projects.Aiming at the problems of high price and shortage of medium-coarse sand in the land backfill project,we research the land backfill and reuse technology of engineering waste soil,and apply laboratory test and field test to analyze the engineering properties and environmental protection characteristics of engineering waste soil,so as the utilization effect of engineering waste soil after environmental protection landfill.The results show that it is feasible to replace medium-coarse sand with engineering waste soil for backfilling,which meets the requirements of environmental protection and has significant economic and social benefits.
