盐渍土地基勘察
salty soil foundation investigation
yanzitud一l一kaneha盐溃土地基勘察(salty 5011 foundat沁n in--vestigation)为盐渍土地基上建筑的设计和施工所进行的工程地质勘察。盐溃土是指土中易溶盐含量高于0.5%，具有吸湿、松胀等特性的土。盐渍土按分布区域分为滨海盐渍土、内陆盐溃土和冲积平原盐溃土;按含盐性质分为氯盐类、硫酸盐类和碳酸盐类盐渍土;按含盐量分为弱盐渍土、中等盐溃土和强盐渍土。 土中所含易溶盐的性质和含量对盐渍土的工程性能影响较大。氯盐类具有较强的吸湿性，使土软化。硫酸盐类具有吸水膨胀失水收缩的特性，使土变松。碳酸盐类盐渍土主要为含Na厂03、NaHC03的土，其溶液具有碱性反应，阳离子吸附性强，粘土颗粒结合水膜增厚，不仅颗粒间的粘聚力减小，而且引起土体膨胀。 勘察工作内容包括:查明盐渍土的分布范围、厚度、形成条件、含盐类型、含盐程度、湿陷性和膨胀性、溶蚀洞穴及其分布;确定场地有害毛细水上升高度;判定土、水对建筑材料的腐蚀性等。勘探点的布置应满足查明盐渍土分布的要求。土试样数量应按不同勘察阶段和不同深度区别对待，即详细勘察比初步勘察、浅部比深部取土间隔要缩小一些。地基承载力的确定应以静力载荷试验为主，辅以其他土的原位试验。土的试验室试验除作一般试验项目和易溶盐分析外，还要进行一定数量的化学分析和有机质含量测定，必要时对土的结构进行电子显微镜鉴定。根据勘察结果，对盐渍土地基进行评价。 (傅世法)
