摘　　要：采取杭州市深基坑工程典型粉质黏土和黏土土样,通过室内土工试验进行了细颗粒含量分析,从PM2.5的定义出发,推算了单位粉质黏土和黏土的环境污染潜力。同时开展室内模拟试验,探究粉质黏土和黏土的环境污染特点。By taking typical clayey soil samples from a deep foundation pit in Hangzhou, the fine particle content of soil samples was analyzed by laboratory soil test. According to the definition of PM2.5, the pollution potential due to the transportation of excavated silty clay and clay was evaluated. Laboratory Dust Raising simulation tests(DRT) were carried out to explore the characteristics of the air pollution by dried silty clay and clay.

关 键 词：基坑开挖 PM2.5 颗分试验 室内模拟试验
