摘要
本文对青岛东北部海域101个表层沉积物样品进行了粒度参数与现场土工特性指标之间的统计分析,获得了研究区沉积环境分区,粒度参数与土工参数之间的相关关系.研究表明,研究区沉积环境可分为滨海沉积环境、过渡沉积环境、浅海沉积环境和残留沉积环境.不同沉积环境的粒度参数与土工参数的相关性都较为良好,但相关关系式具有明显差异.这些关系为利用已有的研究资料反演区域海底的工程地质特征提供依据,为研究区域工程地质条件提供参考.
Abstract
Based on the data of 123 sea samples from Jimo city,Qingdao and the historical investigation data,this paper made a statistical analysis of the relationship between the indoor particle size parameters and the in-situ geotechnical characteristics,and obtained the sedimentary environment division of the study area and the correla-tion between the particle size parameters and the geotechnical parameters.The study showed that the sedimentary environment of the study area could be divided into coastal sedimentary environment,transitional sedimentary en-vironment,shallow marine sedimentary environment and residual sedimentary environment.The correlation be-tween grain size parameters and geotechnical parameters in different sedimentary environments was good,but the correlation formula was obviously different.These relationships could provide a basis for understanding the engi-neering geological conditions of the study area,and provide a reference for inversion of the engineering geological characteristics of the regional seabed by using the existing research data.
