THE BASIC CARRY-OVER METHOD-GRAIN CARRY-OVER AND GRAIN-TO-GRAIN CARRY-OVER OF EFFECTIVE STRESS IN ARBITRARY LEVEL SECTION OF SATURATED SOIL MASS

Li Dingzhou; Zhang Weijiang (Ningxia Agricultural College, Yongning, Ningxia 750105)  
In this paper,according to the description of the basic carry-over method--graincarry-over and grain-t0-train carry-over of effective stress in arbitrary level section of saturatedsoil mass, the formulas of K.Terzaghi effective stress principle are derived. Two facts areexplained that the grain skeleton stress isn't less than the average stress in arbitrary level sectionof soil mass and the creep that resulted from the nonhomogenity of grain stress brings about thestress to approximate average quantity in the same section.Finally, a question about the formula is presented. As is a number which can t be neglected and the correct description: As=(1-n)A.
