土力学复习(国外英文资料) The engineering properties of soil: the complexity of dispersible variability Saturated soil: all the gaps except earth particles are filled with water. When the earth interacts with water, the soil will absorb some water molecules to form a water membrane on the surface of the soil. The characteristics of the junction water characteristics 1 are not met by the gravity control of the surface of the soil and the temperature of the free flow of the two gas knots is lower than that of the normal water The boundary value of the grain group: the large grain group and the coarse grain group 60mm coarse grain group and the fine grain group 0.075 mm gravel and the sand 2mm Granularity: the size of the earth is called granularity. Analysis of soil size: ( 0.075 mm) sedimentation analysis ( 0.075 mm) Group: the soil that is similar in size is often incorporated into groups. The relative content of different granules in soil. The method of granularity composition: tabular method, cumulative curve method, triangular coordinate method Low soil plasticity index: liquid limit WL: transition from liquid to a plastic state soil atterberg limits plastic limit WP: soil by the plastic state transition to a brittle state of atterberg limits. IP = WL - WP plasticity index of the cohesive soil plasticity size, available to measure the moisture content of soil in a plastic state change range, the range is the difference between the liquid limit and plastic limit value, known as plasticity index. Liquidity index IL = a can represent the natural relationship between moisture content and limit moisture content index, namely, liquidity index, W = in liquid limit soil to W = soil in the plastic limit state, the plastic state of soil engineering classification based on: 1, the grain composition characteristics of the soil. Soil plasticity index () 3, soil organic matter existence condition The properties of soil that produce capillary phenomena are called capillarity. Capillary phe
