摘要
鉴于中国普遍存在的带有建筑的人工土坡,利用GEO-studio模拟了降雨量大小对土坡稳定性影响,发现小雨、中雨对土坡的稳定性影响很小,几乎不用考虑;而暴雨及特大暴雨会使土坡失稳。基于灰色关联分析法分析了降雨量、坡高、坡角、荷载及荷载距离与边坡安全系数的关联度,表明其关系为:荷载距离>坡高>坡角>荷载>降雨量。
In view of the ubiquitous man-made soil slope with buildings in China,geo-studio was used to simulate the influence of rainfall on the stability of the soil slope.Moderate rain has little effect on slope stability.Heavy rain and extremely heavy rain can destabilize the slope.Based on the grey correlation analysis method,the correlation degree between rainfall,slope height,slope Angle,load and load distance and slope safety coefficient is analyzed,and it shows that the relation is:load distance>slope height>slope Angle>load>rainfall.
