摘　　要：对不同配比以及不同含水率污泥与生活垃圾(MSW)的混合样进行土工性质测定及堆体稳定性模拟,结果表明:污泥含水率越高,混合样的力学性能越差;混合物料粘聚力c及内摩擦角ψ均随污泥比例的升高先增大后减小。同时,对混填堆体进行稳定性分析发现,对于含水率70%~86%的污泥,占比超过50%时,填埋作业只能坑填,不可堆高作业。Geotechnical properties and landfill stability of the mixed samples were studied with different proportions and water content of sludge. The results showed that the higher moisture content of sludge, the worse mechanical properties of mixed samples, and cohesion force （e） and internal friction angle （ψ） increased first and then decreased with the increase of sludge ratio. Meanwhile, the stability analysis of mixed landfill found that for the sludge with 70%-86% water content, pit filling would be the only operation to be chosen, if the sludge accounted for more than 50%.
