河南省岩土体类型及主要环境工程地质问题刍议

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。

PRELIMINARY DISCUSSION ON ROCK-SOIL MASS TYPES AND MAIN ENVIRONMENTAL ENGINEERING GEOLOGICAL PROBLEMS IN HENAN PROVINCE

Henan Province is located in the Central Plains ,where is specialized in transport facilities,dense population and frequent mankind engineering economic activities.There are the complete morphologic types and complex rock soil mass types.A whole series of questions of environmental engineering geologies have appeared in the constructing projects of reservoir,minerals development,railway and highway.The engineering geologic characteristics in different rock soil mass types are whole different,the environmental engineering geologic problems produced from this are not always identical.To analyse the rock soil mass types and its engineering geological characteristics are the basis of harnessing environmental engineering geologies and preventing and controlling man made calamities.The rock soil mass types and main engineering geological characteristics in Henan Province have been introduced in this paper.The authors have in detail expounded the environmental engineering geological problems produced in the construction of reservoir area,mining area and communications line and provided the geologic basis for harnessing environmental engineering geologies and preventing and controlling man made calamities.
