摘　　要：对吉林林区泥炭质土的物理力学性质进行试验测定．测定了泥炭质土的三相比例指标，并根据三个指标导出了几个其它物理性质指标．测定了样土的液塑限，计算出了液塑性指数．通过压缩试验测定了样土沉降量，计算出了压缩系数和压缩模量．通过样土抗剪试验确定了样土抗剪强度参数，计算出了样土最大承载力．这些基本参数的测定。Physical mechanics character of peat soil was measured in forest area of Jilin.Other physical character quotas derived from three quotas.Liquid plastic limit of sample and Liquid plastic index were calculated.Subsidence quantity of sample was measured by compression test and bulk modulus was calculated.Shearing strength coefficient and maximum load bearing capacity were calculated by shearing test of sample.These basic parametic measurement provided reliable basis for sub grade design of clearing road and construction.
