摘要
本文对大津港东突堤地区千余固结系数试验值进行统计分析,发现对于塑性指数I_p>17的粘土,固结系数值随固结压力的变化具有良好的规律性.文中在提出变化模式的基础上,给出了统计经验公式,并初步分析了这一变化规律的原因.最后用一个结合实际工程所做的算例说明了固结系数回归公式的应用.
A statistical analysis on more than one thousand test readings for the coeffint of consolidation obtained from the East Pier Area of Tianjin Port was conducted and it is found that the coefficient of consolidation possesses a sound regularity with the variation of consolidation pressure when the plastic index (1p) of clay is>17. Based on the presented patterns of variation, the author presents a statistical impirical formula and preliminarily expounds the rea-sons for the patterns of variation. Finally, an example of computation, for a project is presented to interprete the ap-plication of the regression formula for the coefficient of consolidation.
