摘　　要：对南通辖区6个不同土质特点的区域进行江海河沟淤泥取样,对淤泥密度、堆积密度、含水率、塑性指数等进行了测试,并进行颗粒分析。试验结果表明,典型样本大部分颗粒级配较好,塑性指数75.76%处在适合生产烧结砖的范围,同一河道不同河段塑性指数有时相差较大。并按JTG E40—2007《公路土工试验规程》进行试验,对GB/T 50123—1999《土工试验方法标准》测得的塑性指数进行复核。对南通地区淤泥烧结砖原料资源开发利用等提出建议。We took river silt samples from six areas with different soil characters in Nantong and carried out testing on silt density,bulk density, moisture content and plasticity index and analysis of grain sizes. The results showed that most of the typical samples have good particle size distribution,and 75.76% sample＇s plasticity index are in the range of suitable for making fired brick. The silt plasticity indexes of same river in different sections are sometimes quite different. We also checked the plasticity index result from GB/T 50123--1999 ＂Standard Silt Test Method＂ by means of testing in the method of JTG E40-2007 ＂Road Soil Test Procedures＂. Make recommendations on regional development and utilization of raw materials resources of silt fired perforated bricks in Nantong.
