摘　　要：根治盐渍土道路盐胀破坏的病害,关键在于怎样将路基冻土层内的盐分和水排掉,解决盐、水在路基冻土层内的富积问题。本文通过改变盐渍土路基底部结构中隔断层的坡度,增设集水槽,分析测定集水槽内渗透溶液的含盐量得到该路基结构在相应隔断层坡度时的排盐量,模拟盐渍土路基在降雨时的排盐效果来确定适合排盐的最佳坡度。Effect a radical cure diseases of salt heaving damage in saline soil road , the key lies in how to drain the salt and water and solve the problem of salt and water accumulated in the roadbed frozen layer. In this paper, it is to determine the optimum slope for salt discharge according to salt discharge of the saline soil subgrade in the simulated rainfall by changing insulating layer＇slope, and install water channel under the insulating layer and achieving salt discharge amount of the subgrade structure in the corresponding insulating layer＂ slope through the analysis of salt composition of the percolating solution in the water channel.
