摘要
粗颗粒盐渍土是一种特殊的岩土体,由于其独特的结构特征及复杂的工程性能,常常给此类地区的工程建设带来了较大难题。结合大量工程实践和室内外专门试验,在系统总结粗颗粒盐渍土基本特征的基础上,提出了粗颗粒盐渍土溶陷和盐胀的宏观评价标准,即:盐胶结型盐渍土以盐胀为主,盐充填型盐渍土以溶陷为主,以及含盐量、渗透系数的一些具体量值等,该标准的提出,为此类地区粗颗粒盐渍土工程性能的快速、合理评价提供了技术依据。
Coarse saline soil is special soil because of its unique structural characteristics and complex engineering properties,therefore it often cause great construction problems in these areas. Based on a large number of engineering practice and indoor and outdoor special test,this paper proposed the macroscopical evaluation criteria for salt resolving slump and salt expansion of coarse saline soil,which could provide technical basis for the coarse saline soil engineering properties rapid and reasonable evaluation in such areas.
