摘　　要：天然土体往往都具有结构性,通过对土体结构性的研究,进而明确结构性对土体变形的影响,对于土体的力学性状的研究具有重要意义,对于结构性对土体变形的影响,王国欣通过改进李涛的数学模型建立了考虑结构性影响确定先期固结压力的计算关系式,通过进一步将改进的方法确定的先期固结压力用于变形量计算分析中,通过实际的应用与分析,评价了该方法与传统的e-lg p曲线法以及与实际变形情况之间的关系。The natural soil generally has structural property and the research on this structural property and its influence on natural soil deformation is meaningful for the mechanics character studying of soil.WANG Guoxin had set up a calculation formula to calculate the preconsolidation pressure of soil considering the influence of structural property of soil by way of reforming the LI Tao Mathematical Models.By way of further applying the preconsolidation pressure obtained from the modified method to calculate the soil deformation,the relation between this modified method and the traditional curve method and actual deformation results is assessed based on practice and analysis.
