英文摘要	Jin'anqiao Hydropower station is a 160m height concrete gravity dam in Jinsha River, China. Basalts with chloritized joints were distributed in the dam foundation and two banks of low altitude in the hydropower station, and these special basalts were named basalts with chloritized joints. In studying area, basalts were cutting severely by dense chloritized joints. In the light of current code for hydropower engineering geological investigation (GB50287-2006,China), types of rock mass structure should be inlaid cataclastic structure or cataclastic structure, and types of rock mass quality should be grade IV or grade III2, but in situ condition, basalts were closely locked. Through field investigation and analysis, found out that these were new special structure rock masses named inlaid cataclastic structure in situ. These cataclastic structure rock masses were discrete in situ, and differentiated with fracture zone by tectonic process or displacement. The inlaid cataclastic structure rock mass in situ had some characteristics: with quasi integrality, low permeability, high rock mass wave velocity, high deformation modulus. Based on these characteristics, put forward the rock mass structure classification scheme of this new inlaid cataclastic rock mass in situ.
