摘　　要： 本文以压实黄土为对象,以各种改进的仪器设备为手段,在较大的湿度和密度范围内系统地研究了非饱和土的渗气性、渗水性、孔隙水压力和孔隙气压力在三轴不排水不排气剪切过程中的演化特性;用多种方法研究了非饱和土的吸力—密度—饱和度间的关系;在总结正反两方面经验的基础上,摸索出一套相应的测试方法. Air and water permeabilities, suction, evolution properties of pore water pressure and pore air pressure in unsaturated compacted soil are studied over wide ranges of soil moisture and soil density by various improved instruments, i.e., a special triaxial apparatus developed by the authors, a set of facility of air permeability and a set of equipment of water infiltration characterized by measuring water content with gamma rays. Ralationship among suction, degree of saturation and denstity of the soil is established by several methods. Series of realistic methods for testing the engineering properties of unsaterated soils are summarized.
