摘要
实验表明，深部土层的先期团结压力与土层沉积的历史有关；土的团结系数和渗透系数均随压力的增大而减小，并在高压下趋于稳定；当压力小于先期团结压力时，土的次团结系数与压力关系不大；当压力大于先期固结压力时，次团结系数随压力的增大而增大。
he high pressure consolidation tests of soil samples indicate that the preconsolidation pressure is related to the sedimentary history of soil layers. The coefficients of consolidation and Permeability decrease with the increase of pressure and tend to certain stable values under high pressure. When the pressure is less than the preconsolidation pressure, the coefficient of secondary consolidation has no relation to the pressure. When the pressure is larger than the preconsolidation pressure, the coefficient of secondary consolidation increases with pressure.
