Station at Jinsha River[J]. 2006, 27(S2).DOI:
The engineering characteristic of left bank B2 debris of jinanqiao hydropower station is studied
especially for the distributing form and distributing characteristic of tuff interlayer.The stability and potential failure form of B2 debris caused by tuff interlayer are also discussed. The stability of B2 debris is analyzed by 2D finite element method and limit equilibrium balance method. The conclusion isdrawn that the safety factor of B2 debris along the bottom of B2 debris can fulfill the engineering reguirement.Furthermore
this paper suggests more study on the characteristic of immersion tuff interlayer and monitoring with feed back analysis in time
