摘要
持续降雨条件下,边坡浅层所形成的暂态水头变化对边坡稳定性具有重要的影响,一直是水工渗流研究领域内的热点和难点。鉴于当前理论上和技术上的困难,提出了根据降雨量及岩体的孔隙度估算边坡浅表中暂态水头大小的新方法,并结合工程实例对高边坡不同降雨情况下的暂态水头进行了计算,计算结果基本合理。从而为工程上边坡暂态水头的计算提供了一种简单的估算方法。
Effect of transient head change under persistent rainfall on the stability of geo-slope is obvious, and it is always the focus and difficult point in geotechnical engineering or related fields. Because current theory and technology are all difficult to calculate transient head precisely, a new method to calculation transient head based on rainfall quantity and porosity of rock mass of geo-slope was presented. According to a actual engineering casing, transient head values were calculated under different rainfall strength and the results were reasonable compared with observed values. A simple method to estimate transient head under persistent rainfall in engineering fields was provided.
