| 中文摘要 | 在分析国内外泥石流预报的基础上，结合泥石流形成机理研究取得的进展，提出了新型的暴雨泥石流预报方法。通过蒋家沟泥石流源地人工降雨试验，坡面泥石流形成与源地土体特征参数变化存在密切的关系。暴雨泥石流形成的过程可以描述为：降雨→土体含水量、土体结构和土体组成的变化→土体强度变化→斜坡稳定性变化→坡面泥石流形成→沟谷泥石流。建立起前后两者的关系。用降雨并结合中间关系方程分析泥石流发生的概率、时间及形成规模等参数，逐步提高泥石流预测预报精度。比传统的预报方法在精度上有很大的提高，使对误差进行估算成为可能。 |
| 英文摘要 | Abstract：On 26 December，2004，a strong earthquake of magnitude M = 9 ． 0 struck the close northwest sea of Sumatra island in Indonesia，and its magnitude scale is very infrequent in nearly 100 years in the world ． It was accompanied by tremendous tsunami whose wave runup was neady 10m， and the wave reached shallower water near the coast， and it shortened，slowed and gathered into surges that killed approximately 300，000 people across a dozen countries in the southeast Asia， the south Asia and the east Africa． Because of the earthquake tsunami， lan dform deform ation of some islands in Indonesia and Thailand changed，and most salina—alkali land left in the affected countries．A long distan ce rupture in the edge of Sumatra plate accumulated enorm ous energy，and it released on 26，which resulted in the earthquake tsunami．Large magnitude scale，sudden happening of the earthquake tsunami，dense population in the affected areas，and the scarcity of knowledge and experience of tsunami，no Indian ocean tsunami warning system as well，are the reasons of tremendous casualties in this tsunami catastrophe．Th ere exists probability of the earthquake tsunami in the sea from Taiwan to Hainan in China， therefore the tsunami warning system should be improved， the prevention disaster standard of construction engineering in the coastal region should be enhanced，the construction of prevention wave dikes should be s(rengthened，and the bio—engineering measures，for example，restoration of mangrove and other bio-engineerering etc，to prevem the potential tsunami disasters should be taken． |
