摘要
该文根据水平截面的力平衡原理,分析土骨架传递力、孔隙水压力作用力与土重、水重之间的关系,指出有效力是土骨架重力与浮力之差,中和力是重力水重力与土骨架浮力之和。同时,推导出土骨架浮力和浮重度计算公式,土骨架所受浮力是在阿基米德定律上的折减,折减系数与给水度有关。
According to the force-balance principle in horizontal section,this paper analyzes the relationship between the transfer force of soil skeleton,the pore water pressure force and the soil weight and the water weight.It's pointed out that the effective force is the difference between gravity and buoyancy of soil skeleton,and the neutralizing force is the sum of gravity of water gravity and buoyancy of soil skeleton.Meanwhile,the calculation formulas of buoyancy and buoyancy weight of soil skeleton are deduced.The buoyancy of soil skeleton is reduced according to Archimedes'law,and the reduction coefficient is related to water yield.
