From these researches as above, this paper found a new method to analysis salty soil road engineering properties by phase equilibrium theory, which provides a new angle of analysis on salty soil properties, experiment and engineering practice in these ways as follows:(1) Analysis the disadvantage of traditional salty soil experiment;(2) Analysis the disadvantage of current salty soil definition by phase equilibrium theory, and gives the chart of distinguish salty soil by the condition of hydrography and climate change;(3) Analysis the mechanics of subgrade frost boiling based on the change rule of liquid content;(4) Based on the change rule of ingredients content and volume in salty soil, analysis the mechanics of subgrade salt heaving and the restraining method by adding sodium chloride.

通过以上研究，本文初步建立了以相平衡理论为核心的盐渍土路用工程性质分析方法，该方法对盐渍土工程性质的理论分析、试验研究以及工程实践提供了新的研究思路与方法，具体体现在：(1)分析了传统的盐渍土试验存在的缺陷；(2)分析了现行盐渍土定义的不足，并以相平衡理论为基础，结合水文、气候条件的变化给出了判别盐渍土的诺谟图；(3)分析了盐渍土盐溶液含量的变化规律，并从盐渍土含液量变化规律出发，分析了盐渍土路基较非盐渍土路基翻浆严重的机理；(4)分析了盐渍土各固相含量及其体积的相变规律，并在此基础上分析盐渍土路基的盐胀机理，以及采用添加氯化钠来抑止硫酸盐盐渍土的盐胀机理

So the systematically study of loess landslides are emergently needed. Based on detailed investigation and survey of characteristics of environmental geology, engineering geology, hydrometeorology in Tongchuan, the distribution characteristic and the outer, inner factor of loess landslides are studied; and it is concluded that the rainfall and artificial engineering activity are the leading causes of loess landslide among various factors. Through plenty of tests of soil samples, it is researched that the loess"s physical mechanics characteristics, the loess landslide"s formation mechanism and kinematics mechanism.

本文在详细调查和勘察铜川地区的环境地质、工程地质及气象水文特征的基础上，对黄土滑坡的分布特征和滑坡形成的内外因素进行了深入剖析，认为在各种影响因素中，大气降水和人类工程活动是铜川黄土滑坡的最主要的诱发因素；在采集大量的土样并进行试验的基础上，对黄土的物理力学特征和黄土滑坡形成机理、运动学机理进行了研究，推导出了滑坡运动机理中的孔压参数A_D、B_D分别与孔隙比和饱和度的统计关系。
