摘要
清渔河间地块地处湖北省宜昌市,岩溶形态多样,地下暗河强烈发育,为典型岩溶发育区之一。宜昌为湖北省副中心城市,也是中国重要的交通枢纽,岩溶暗河的发育为交通基础设施建设带来极大不便。通过搜集资料分析、大面积工程地质测绘、水文地质调绘和地下多元化示踪试验等综合勘察方法,研究清渔河间地块岩溶发育特征、发育规律,查明了暗河空间分布特征和联通性。根据研究结果,结合地质构造特征,将清渔河间地块的岩溶发育划分为了5个大区和19个亚区。通过对清渔河间地块地形、岩性、构造和气候等岩溶发育控制因素的研究,结合每个岩溶区发育特点及工程建设类型,为工程建设提供了通道,为以后地方建设提供科学依据。
Qingyu River Region is located in Yichang City,Hubei Province,with highly developed karst and many underground rivers.It is one of the most typical karst areas in China.As a deputy central city of Hubei Province and an important transportation hub of China,Yichang City has suffered great inconvenience from the highly developed karst areas and underground rivers.This paper mainly explored the characteristics of karst in Qingyu River Region,and determines distribution of underground rivers,through desk-study,large-scale geological surveying and mapping,and multiple tracer tests.In accordance with the investigation results and geological conditions in Qingyu,karst developed in Qingyu River Region was divided into five large regions,which is further divided into 19 small regions.In addition,this paper also identified the factors that strongly affect development of karst in Yichang,which provide scientific support and guidance for local engineering projects with similar geological conditions in Yichang.
