摘　　要：对兰州地区某工程垃圾地基土进行了表层开挖、灰土紧密和换填夯实的综合技术处理.利用原位现场静载荷试验,研究了垃圾土处理前后的变形性能、承载力和变形机理,为工程基础选型提供了依据.The synthetic ground treatment technique including the excavation of surface layer of garbage foundation soil,the ramming of lime earth, and the compack pressing of back filled soil was applied in an engineering project in Lanzhou region. Based on the location load test, the problems of deformation performance, bearing pressure and metamorphosis mechanism of treated garbage soil were studied. In the end, some suggestions were proposed for the reference to foundations chosen.

关 键 词：垃圾地基土 载荷试验 承载力特征值 变形量
