河南省地处中原，交通发达，人口稠密，人类工程经济活动强烈。全省地貌类型齐全，岩土体类型复杂。在水库建设、矿产开发和铁路公路建设中出现了一系列环境工程地质问题，岩土体类型不同，其工程地质特性各异，产生的环境工程地质问题亦不尽相同。分析岩土体类型及其工程地质特征，是治理环境工程地质问题、防治人为灾害的基础。本文介绍了河南省岩土体类型及其主要工程地质特征。对水库区、采矿区及交通建设中出现的环境工程地质问题进行了详细论述，为治理环境工程地质问题、防治人为灾害提供了地学依据。
Henan Province is located in the Central Plains, developed traffic, densely populated, strong economic activities of human engineering. The province has complete types of landforms and complex types of rock and soil. A series of environmental engineering geology problems have appeared in reservoir construction, mineral development and railway highway construction. Different rock and soil types have different geological and engineering characteristics, and environmental engineering geological problems are also different. Analysis of rock and soil types and their engineering geological features is the basis for the management of environmental engineering geological problems and prevention and treatment of man-made disasters. This paper introduces the rock and soil types and the main engineering geological features in Henan Province. The paper discusses in detail the environmental engineering geology problems in reservoir area, mining area and traffic construction, which provides the basis of geology for controlling environmental engineering geological problems and preventing and controlling man-made disasters.
