重庆羊角滑坡群滑带土抗剪强度研究

Study on shear strength of slip soil of Yangjiao landslides group

羊角滑坡群是乌江白马航电枢纽坝前的一个巨型滑坡群,该滑坡群的稳定与否,对白马航电枢纽的安全运行至关重要。为能给该滑坡群的治理工程设计和稳定分析提供准确的强度参数,对该滑坡群中各滑坡的滑带土抗剪强度进行研究。采用滑带土室内试验、现场大剪试验、反演分析等方法,确定了羊角滑坡群各滑带土的抗剪强度参数,为工程设计提供了可靠的数据。

Yangjiao landslides group is a large scale landslide group in the upstream area of Baima Navigation-power Junction on Wujiang River.The stability of the landslide group is crucial to the safety of Baima Navigation-power Junction.In order to provide accurate strength parameters for stability analysis and regulation project design of the landslide group,the shear strength of slip soil of Yangjiao landslide group is studied.The shear strength parameters of slip soil are determined through laboratory experiment of slip soil,in-situ large scale shear test,and inverse analysis.
