摘要:

2004年开始在江西地质灾害易发区内建立了8个滑坡灾害监测点。通过定点监测试验、历史资料的统计分析和应用滑坡稳定性原理等方法, 揭示了我国东部丘陵区降雨诱发滑坡灾害的形成机理。分析表明, 降水对滑坡的诱发作用, 不仅取决于当日雨量, 而且与前期过程降水量有关, 但前期各日雨量的影响程度是不相同的; 饱和状态下的滑坡, 其稳定性主要与滑坡的条块重量(W)和总的孔隙水压力与总的上浮压力之比(ru)有关。在监测试验和统计分析的基础上, 建立了滑坡稳定性预报预警报的数学模型, 确定了滑坡灾害发生时的降水临界值。应用Web-GIS技术, 建立了滑坡灾害预报预警的实时业务系统。在近年来的预报服务中, 多次成功地发布了滑坡灾害预报和警报, 取得了明显的成效。

Abstract:

Eight landslide disaster monitoring stations have been established in the regions where geological disaster took place frequently since 2004. Using the observation and analysis of the statistic data as well as the principle of landslide stability, we finally mastered the principle of how landslide took place on account of the continuous rain at the hilly land in the east of China. The study makes it clear that weather or not the rain conduce landslide not only depends on the real time precipitation rainfall, but also has relevance to the previous volume from weather process, however the influence of daily rainfall is absolutely different. In the saturation condition, the stability of landside is related with the ratio of the total pressure of interstitial water to the total uplifting pressure besides the weight of the Landslide strips. Based on the experiment and statistics, the model of Landslide disaster forecasting and warning with the very critical precipitation rainfall has been founded. By combining the Web-GIS technology with the spatio-temporal forecast of Landslide disaster, the real time system has been established by which the products of the Landslide disaster forecast are automatically promulgated. It is prove to be effect in the forecast service in the last years for successfully promulgating forecast and warning several times by which there are several hundreds of people and more than thousand million of property survived.

Key words: Landslide disaster    Dynamic model of stability    Daily integrated effective rainfall    Web-GIS Technique    Forecasting and w arning
