关于长江三峡库区重庆段c、φ取值的探讨

An Approach to the Geotechnical Parameters c and? for Landslides in the Yangtze Gorges Reservoir Region, Chongqing

基于滑坡参数取值对滑坡稳定性评价影响重大,本文运用各种方法对岩土力学参数指标c、φ取值问题开展研究。研究结果表明,综合运用多种方法,可以达到合理选择岩土的力学参数c、φ值的目的,避免人为降低设计参数、增大工程投资或c、φ取值偏高给工程安全带来隐患的问题。

Geotechnical parameters c and φ are of great importance to Stability of a landslide. This paper makes an approach to determination of parameters c and φ for landslides in the Yangtze Gorges reservoir region, Chongqing. The study indicates that reasonable c and φ values can ensure safety in engineering and cut down engineering expenses.
