| 英文摘要 | In recent years, with the rapid development of highway construction in china, slope disasters are becoming more and more frequent. According to statistics, about 90% slope disasters are induced by rainfall especially torrential rain or continuous rain. In this paper, based on the statistic analysis of slope geological disasters since 2000 in Hunan province, the relationship of rainfall characters and slope disasters has been discussed. Further more, numerical simulation method based on saturated unsaturated seepage flow theory is used to study the influence of rainfall intensity rainfall (titration and rainfall type to slope stability and the traditional effective rainfall model is advanced. By combining the advanced effective rainfall model with the statistic data of slope disasters in Hunan, the effective rainfall area pre-warning values for slope disaster in Hunan province are suggested as: 0-30mm is for no risk, 30-63mm is for low risk, 63-95mm is for middle risk, 95-133mm is for high risk and more than 133mm is for large risk. |
