流泥的工程特性分析研究

Analysis on Engineering Characteristics of Quick Mud

针对我国沿海港口中黄骅港、深圳港、连云港港、天津港4个地区的代表性流泥进行室内试验分析,并对黄骅流泥进行了室内大型模型槽真空预压试验。分析认为,黏土矿物的种类与含量是影响淤泥性土强度的主要因素;淤泥性土含水率和其十字板强度之间存在着良好的相关关系;采用真空预压法加固大面积高含水率的超软土要进行现场试验研究。

The representative quick mud in Huanghua Port,Shenzhen Port,Lianyungang Port and Tianjin Port,which are the coastal ports in China,was tested in laboratory and the test results were analyzed,the vacuum preloading test of the quick mud in Huanghua Port in a large indoor testing flume was carried out.The test results show that the amount and the type of clay minerals are primary factors which impact the vane strength of quick mud,the decrement of water content and increment of vane strength of quick mud in the process of soil improvement at Huanghua Power Plant have good correlation;Large-area ultra soft soil improvement with the vacuum preloading method must be analyzed through field test.
