针对浙江省如杭州、温州和宁波等地的陆域软土灵敏度一般在4左右，而舟山地区的海域软土灵敏度高达8这一现象，对舟山和温州两地的软土性状分别进行试验研究，包括常规土工试验、土体微结构电镜扫描、土中元素成分分析和矿物成分分析试验，探讨舟山土高灵敏度成因，并对物理力学形状进行研究。试验研究发现，舟山土相比温州土，液性指数更高，结构性更容易破坏，微结构排列更加松散无序，氯和钠元素含量更高，原生矿物含量更小而黏土矿物含量更高，这些试验结果能从不同角度解释舟山黏土和温州黏土灵敏度的差别。结果表明，舟山黏土高灵敏度的成因绝不是单个因素的影响，而是各种因素综合影响所导致的。

In Zhejiang province ,the sensitivity of soil in Zhoushan area is up to 8 w hile the average value is 4 in Hangzhou ,Wenzhou ,Ningbo ,etc .areas .In order to investigate the cause of such a high value of sensitivity of Zhoushan soils ,experimental study on Zhoushan and Wenzhou sensitive soils was conducted and compared in this paper ,including conventional geotechnical tests ,the scanning electron microscope (SEM ) observations of microstructure , the energy dispersive X‐ray spectroscopy (EDS ) composition analyses and X‐ray diffraction analyses of clay mineral compositions .As compared with Wenzhou soils ,the liquidity index of Zhoushan soils is larger ,the structure of Zhoushan soils tend to be destroyed easier ,the microstructures of Zhoushan soils tend to be more loose and disordered , the contents of chlorine and sodium elements are higher and the contents of clay mineral are also higher of Zhoushan soils . It is conducted that the sensitivity difference of Zhoushan clay and Wenzhou clay are caused by various comprehensive factors .
