浅谈典型场地盐渍土地基的病害特征及治理对策

Discussion on Damage Characteristics and Control Measures for Typical Saline Soil Foundation Sites

盐渍土的盐胀性是产生地基病害的主要原因之一。通过调查典型盐渍土地基的病害特征,分析了场地的工程地质环境及盐渍土的分布规律,进而系统分析了场地产生盐胀的影响因素,影响因素包括地基土、有害含盐量、毛细水上升、天气气候、地形地貌等。最后根据针对场地的盐胀病害,提出了较为可行的防治措施,对盐渍土病害的处理具有一定的借鉴意义。

Salt expansion of saline soil is one of the most important factors to produce the disease of foundation. Through the in- vestigation of typical disease characteristics of saline soil and the analysis of the engineering geological environment of the site and the distribution of saline soil, the paper systematically analyzed the factors affecting the expansion of the site. The factors include the foundation soil, harmful salt content, capillary water rise, weather, climate, topography, etc. Finally, according to the site＇s salt expan- sion disease, The feasible control measures is put forward ,which has certain reference significance to controlling saline soil harm.
