Superficial View on Division of Rock Mass Weathering Zones in Engineering Geology for Construction of Hydropower Projects

This paper gives a brief account of effect of rock mass weathering on construction of hydropower projects and importance of its rational zoning; expounds rock mass weathering, weathering effect, weathering - resistance capability and factors influencing weathering process of the three major rock categories as well as classification of features of rock mass weathering; presents the new Specifications for Engineering Geological Prospecting for Construction of Hydropower Projects to divide rock mass weathering zones and its application; puts forward the principles and method of dividing rock mass weathering zones; and raises points for attention in division of rock mass weathering zones.
