| 摘 要： | 对浙江省典型海涂土进行大量实测的结果表明:海涂土外附力远高于水田土壤。粘粒含量愈高,外附力愈大。外附力与含水量呈二次曲线关系;与机具比压、载荷作用时间呈线性关系。机具常用材料钢和橡胶对外附力影响不显著。海涂土最大外附力是分层的,以土层10cm上下处为分层界面。为减少粘附,机具可采用浮式或密齿式行走装置。

| Abstract: | Through a great deal of tests to main coast saline soil in Zhejiang province,the results showed that the adhesion of coast saline soil was larger than paddy soil. The higher the clay content , the larger th adhesion. The relation between adhesion with moisture content was quadratre square curve,and that between specific pressure of machinery and acting time was linear. The effect of different material (rubber and steel) on adhesion was not marked. In addition,it suggested that the maximum adhesion of coast saline soil was seperated into layer,and about 10 cm depth was the dividing line of the layer. According to adherent characteristic of coast saline soil, it was put forward to structure and requirements of agricultural machinery working in coast saline soil. |
