摘　　要：为研究广东丘陵地区风化花岗岩类土质边坡稳定性影响因素及防护措施,基于广州某区风化花岗岩类土质边坡项目,从地形地貌、地层岩性、气象条件特点等方面进行影响因素分析,并建立模型开展降雨强度、降雨持续时间对边坡稳定性的影响分析研究。从生态护坡角度研究并提出采用截排水设计与生态护坡结合的设计建议,从而更好地解决广东地区土质边坡发生浅层滑坡、崩塌型地质灾害的问题。Based on the weathered granite soil slope project in a district,which to study the influencing factors and protective measures of the stability in Guangzhou.The influencing factors were analyzed from the aspects of topography,formation lithology and meteorological conditions,and a model was established to analyze and study the influence of rainfall intensity and duration.The interception and drainage design with ecological slope protection have been suggested,in order to solve the problem of shallow landslide and collapse type geological disaster in soil slope region of Guangdong Province.
