摘要

随着固结时间的增加

试样逐渐变硬的硬化效应使软粘土的动剪切模量增大;同时

随着固结时间的增加

试样高度和直径明显减小的尺寸效应

也使软粘土的动剪切模量受到显著的影响。通过软粘土自振柱试验

分析了固结时间对软粘土的最大动剪切模量、动剪切模量比和试样尺寸的影响;根据自振柱试验的基本原理

分析了试样尺寸的变化对软粘土动剪切模量的影响;结合试验得到的固结时间和试样尺寸的关系

分析了固结时间通过试样尺寸对软粘土动剪切模量的影响。

Abstract

The hardened effect that represents the soft clay harden gradually with the increment of consolidation time

makes dynamic shear modulus of soft clay increasing;meanwhile

the size effect that represents the height and diameter of the sample decreasing gradually

also produces effects on dynamic shear modulus of soft clay.A serial of free vibration column tests of soft clay is conducted to analyze the effects of consolidation time on maximal dynamic shear modulus

dynamic shear modulus ratio and sample’s size of soft clay.According to the basic principle of the free vibration column test

the effects of varied sizes of sample on dynamic shear modulus of soft clay are analyzed.Combined with the relationships between consolidation time and sample′s size obtained from the tests

the size effects of consolidation time on maximum dynamic shear modulus of soft clay are analyzed.
