| 摘 要： | 本文借助于室内和原位测试方法,以福建泉州花岗岩残积土为例,研究了残积土的基本工程地质特性、微观结构特性、动剪切模量、动应力-应变关系和时间效应,并将其与粘土及砂土进行比较.从大量的共振柱试验和动三轴试验,得到该土饱和及非饱和时的动力参数,非饱和效应,动应力-应变关系以及时间效应的变化规律,并用原位SASW(表面波颇谱分析)法验证了动力参数G_0的可靠性.

| Abstract: | This paper presents the results of the study made with laboratory and in-situ testing methods conducted into
the basic engineering geological properties, microstructural characteristics, dynamic shear modulus, dynamic
stress-strain relationship, unsaturated effects and time effects of Quanzhou latentic soil, and comparison of them
with those of cohesive soil and sandy soil. From the results of resonant column tests and dynamic triaxial tests
carried out,the laws of various aforesaid qualities of the latentic soil have been revealed. The reliability of the
dynamic parameter G_0 is also verified by means of in-situ SASW (spectral analysis of surface wave) method. |
