| 摘 要： | 舟曲“8．8”特大山洪泥石流灾害损失惨重，举世瞩目，灾难发生后泥石流隐患依然存在，灾后重建中面临的第一个难题便是灾后重建工程设防标准的确定问题。通过分析激发“8．8”舟曲特大山洪泥石流灾害降水的时间与空间分布特征，认为本次降水具有强度大、历史短，局地性强的特征。基于此，建议灾后重建工程的泥石流综合治理工程设计中应充分根据本次降水的特征，考虑最不利的极端条件下即按此次降水雨强涵盖整个三眼峪流域范围所产生的最大流量。

| Abstract: | Zhouqu 8.8 extremely big debris flow caused severe damages and has been the world focus.Potential debris flows still exist after the 8.8 disaster.The first difficulty that the government faces during post-disaster reconstruction phase is the determination of the fortification standard of the reconstruction works.Based on the analysis of the temporal and spatial distribution characteristics of the rainfall which triggered the 8.8 Zhouqu extremely big debris flow,we found that the rainfall has characteristics... |
