摘要
本文在分析了大量的地质钻探资料的基础上,提出了互层土的概念;并在模拟地震条件下,对互层土的动力特性,作了初步的试验研究;分析了互层土的动剪模量、阻尼、动强度和孔隙水压力变化的某些特征,给出了动剪模量的修正系数和动、静强度的比值;为海洋工程建设提供了必要的数据。
On the basis of the analysis of a large quantity of borehole surveying data, this paper presents a soil interbedding concept. The dynamic characteristics of interbedding soil are moduled under earthquake conditions and given a preliminary analysis. After a study of dynamic/shear modulus, damping and dynamic strength of interbedding soil and its some characteristics of changes in pore water pressures, the correction coefficient of dynamic/shear modulus, the ratio between dynamic strength and static strength are given to provide offshore engineering installation with necessary data.
