【摘要】 粉土中砂粒、粉粒、粘粒都存在,有着既不同于砂土也不同于粘性土的工程性质。淮安市区粉土由于粉粒占绝对优势,砂粒很少,使其液化特性又表现出不同于普通粉土的区域性特性。在总结国内外粉土地基液化评价及预测的研究成果、分析了其对淮安市区粉土的适用性的基础上,结合区域工程地质特征及土层分布等情况,对淮安市区粉土的液化可能性评价及研究方法提出了有益的思考。更多还原

【Abstract】 Because of having three kinds of properties,i.e.,sand content,silt content and clay content,silty soil is one of the engineering soils in nature of special interest,with distinct characteristics from those of sand and cohesive soil.And the silty soil in Huai’an city has a extremely large silt content and thimbleful sand content,its liquefaction potential will be different from the other silty soil.The main methods for predicting silt liquefaction potential,are firstly summarized.Then on the basis of geology and the engineering character of the regional silt soil,the possible evaluation and studies of the silt soil site are also suggested.更多还原
