长江三峡库区巴东红石包滑坡深层潜在滑移软弱带的研究

RESEARCH ON DEEP LATENT SLIP WEEK BED OF BADONG HONGSHIBAO LANDSLIDE IN THE THREE GORGES RESERVOIR REGION

滑坡勘察中关键问题是滑移带及其力学参数的确定。本文介绍长江三峡库区巴东县某地斜坡,依据多种手段勘察成果的系统分析所确定的深层潜在滑移软弱带;由不同试验条件下的大量试验成果,提出潜在滑移软弱带在各种状态下的力学参数。经施工验证潜在滑移带的确定基本无误,其力学参数审查专家一致认为,试验分析方法正确,取值合理。

The determination of slip bed and its mechanical parameters are keys to landslide investigation. In this paper, it is introduced that deep latent slip week bed is determined according to systimatical analysis of investigation achievement of many methods in some slope of Badong of the Three Gorges reservoir region. It's also introduced that the mechanical parameters in different status of latent slip weak bed are given based on many experiments . Through construction verifications, the determination of latent slip bed is correct. All the appraisal experts consider the test analysis methods is right and the choosing valuse of mechanical parameters are reasonable.
