摘要
根据SARMA法的基本思想,考虑非饱和带基质吸力和暂态附加水荷载对岩体边坡安全稳定的影响,提出了考虑雾化雨入渗效应的边坡稳定性分析方法——改进SARMA法,并将此法应用于紫坪铺2#导流洞出口高边坡工程,进行了边坡在泄洪雾化雨入渗影响下的安全稳定性计算与评价分析。
Based on the basic idea of SARMA method, the slope stability analysis method which can take the influence of atomized rain infiltration into account and the modified SARMA method, are put forward after taking into consideration the matrix suction of unsaturated zone and the temporary additional water load. This method and correlative program have been applied to stability evaluation analysis of 2# high slope of Zipingpu Hydropower Station. Computed results show that atomized rain infiltration and temporary saturation zone are important factors for safety stability of slope, the safety factor of slope will decrease because of atomized rain infiltration. At the same time, reinforcing the protection of slope effectively and reducing the infiltration of slope can improve the safety stability of slope effectively.
