Factors analysis on stability of rock bedded slope

FENG Jun~1,LU He-lin~1,LI An-hong~2〖HJ〗(1.Southwest Jiaotong University,Chengdu 610031,China;2.The Railway Second Survey Design Institute,Chengdu 610031,China)  
Based on finite element analysis,this thesis makes a study on some key factors about stability of rock bedded slope using the laminated model.The results of the analysis come to the conclusion that when the intersecting angle between the strike direction of slope and which of strata exceeds 30°,the possibility of bedding slide of bedding stratified rock slope is little,and this kind of slope may not defined as rock bedded slope.And the computed results are consistent with the results obtained in modeling tests.The relation between the stability of rock bedded slope and the dip angle of strata or the shear strength of joint is also explained.These conclusions can be used as a conference in research,design and construction of rock bedded slope.
