本文在大量固结试验资料分析的基础上,建立了e～p曲线的关系式;导得了确定先期固结压力的计算式,从而弥补了长期以来采用casagrande法时最小曲率半径难以确定或因人而异的缺陷.本文导得的沉降计算公式仅与土中应力有关而与孔隙比无关,因此,在采用分层总和法计算沉降时不再依赖于e～p曲线. Based on the analysis of a large number of consolidation test data, this paper establishes the relational expression of the e~p curve, and derives the calculation formula to determine the preconsolidation pressure, which makes up for the long time that the minimum radius of curvature is difficult to determine or cause by the casagrande method. Different defects. The settlement formulas derived in this paper are only related to the stresses in the soil and have nothing to do with the ratio of voids. Therefore, when using the stratified summation method to calculate settlement, it no longer depends on the e~p curve.
