permeability coefficient of soil的意思|示意

The distribution law of pressure potential in saturated soil using two-ring infiltration method to determine the permeability coefficient was different to that using cutting ring method.

当采用双环入渗法和环刀法测定土壤的饱和渗透系数时，土壤剖面土壤水压力势分布规律不同。

Finally, the influence induced by variation of dynamic coefficient of permeability on soil displacement and stress under harmonic vibration load is investigated.

根据算例，研究了在周期荷载作用下，地基中的超静孔隙水压力、位移的幅值随动力渗透系数变化的一般规律。

The method can be used for measuring the vertical saturation permeability coefficient of the soil outdoors quickly and accurately.

该方法可用于野外迅速准确的测定土壤垂向饱和渗透系数。

The pore water permeability coefficient of unsaturated expansive soil is controlled by suction, cell pressure, dry density and degree of saturation of soil samples.

压实膨胀黏土水渗透系数受吸力、围压、干密度、饱和度等因素控制。

Four kinds of amendments can improve soil physical properties. Soil bulk density decreased, soil porosity, permeability coefficient and field capacity increased under treatments.

四种改良剂均能不同程度的改善土壤物理性状，能降低土壤容重，提高土壤总孔隙度，加快渗透速度，增加田间持水量。

By using this model the soil-water characteristics and permeability coefficient of unsaturated soil are deduced and expressed in fractal dimension and air-entry value.
