以生活垃圾为地基的工程事例越来越多,但垃圾土的处理方法还没有形成系统的经验和成熟的设计计算理论.经过统计分析,按一定配比制备了人工垃圾土,分别进行了未降解、降解旺盛期、降解稳定期在水泥掺入量为25 %、35 %、45 % 3种条件下不同养护龄期水泥垃圾土的无侧限抗压试验,得到了硬化的应力-应变关系曲线和水泥垃圾土强度随养护龄期、水泥掺入量、降解阶段变化的规律.试验结果表明,垃圾土中的有机质既对水泥垃圾土有加筋作用,也有减弱水泥垃圾土强度形成的作用;未降解、降解旺盛期、降解稳定期水泥垃圾土的强度变化特性不同,水泥只对降解稳定的垃圾土有较好的处理效果.同时建议水泥的掺入量应大于35 %.

There are more and more reports of construction on municipal solid waste landfills. But there are no systematic experiences and perfect design method for improvement of municipal solid waste. According to statistical results from national municipal solid waste landfills, artificial municipal solid waste was made. The unconfined compressions of artificial municipal solid waste were tested in under-degradation or in-degradation or past-degradation, mixed with cement 25 %, 35 %, 45 % at different maintenance periods. It is obtained that hardening stress strain curves and the strength law of artificial municipal solid waste mixed with cement versus maintenance period and cement content as well as degradation phase. The test results show that the organic constitute in artificial municipal solid waste can reinforce and weaken the artificial municipal solid waste mixed with cement. There are different strength characteristics of artificial municipal solid waste mixed with cement at different degradation phases. Only municipal solid waste at past-degradation can be better improved. It is suggested that the cement content is more than 35 %.
