概述了国内外关于地基摩阻力及地基摩阻系数的研究现状,对地基摩阻力系数进行了试验研究,提出了观测地基摩阻力系数的一种较为可行的试验方法。通过试验给出了板底摩阻系数的影响范围以及摩阻力系数变化对连续配筋混凝土路面的性能影响,根据试验数据进行线性回归,得到地基摩阻力弹性阶段和塑性阶段的本构关系,即得到地基摩阻力双线性模型。
The current research status of friction resistance and ground friction coefficient of foundation are summarized. The friction coefficient of foundation is experimentally studied, and a more feasible test method of observing friction coefficient of foundation is proposed. The influence range of the friction coefficient at the bottom and the influence of the coefficient of friction on the performance of continuous reinforced concrete pavement are given through experiments. Based on the experimental data, the linear regression is performed to obtain the constitutive relation between the elastic phase and the plastic phase of the foundation frictional resistance Obtain the bilinear model of friction resistance of foundation.
