School of Civil Engineering, Beijing Jiaotong University, Beijing100044, China

摘要

摘要: 以平板载荷试验为基础，结合地基系数K₃₀、二次变形模量E_v2和动态变形模量E_vd的实验方法，对三者的概念和物理意义及运用平板载荷试验对其进行测试的原理进行了介绍。以D-P模型为基础，对不同参数土体的K₃₀，E_v2，E_vd进行了仿真分析，得出7组K₃₀，E_v2，E_vd的数值。最后用线性回归的方法得出了K₃₀与E_v2，K₃₀与E_vd的线性关系表达式及线性相关系数。结果表明，K₃₀与E_v2，K₃₀与E_vd都具有很高的线性相关程度，且数值模拟得出的线性拟合关系与实际现场的试验结果比较接近。

Abstract: Based on the plate loading tests, the concept and physical significance of the coefficient of soil reaction, modulus of deformation and dynamic modulus of deformation as well as the test principle are introduced combining with the test method. Taking D-P model as the example, seven groups of values of the coefficient of soil reaction, modulus of deformation and dynamic modulus of deformation are calculated. The linear representations and coefficients of linear correlation of modulus of deformation and coefficient of soil reaction, dynamic modulus of deformation and coefficient of soil reaction are acquired. The results indicate that they have a high level of linear correlation, and their expressions are closely to the actual situation.
