| 摘 要： | 汶川地震使牛眠沟流域变成了一个多泥石流灾害的区域,到目前为止,已经发生7次大规模泥石流灾害.经研究,该流域诱发泥石流灾害的3个基本条件非常发育,而目前正处于发展阶段,在震后5～10年内的雨季,极易发生危害性较大、冲击力较强的大规模降雨型泥石流.如果考虑直接利用主沟内沉积的泥石流堆积物,在主沟堆积区的中上游左右两侧修建约...

| Abstract: | After Wenchuan earthquake,Niumiangou valley becomes an area with dense and frequent debris flow disasters;so far,seven large-scale debris flows occurred.In this valley there are three basic conditions making debris flow well develop, and so it is in a developing stage now.Thus the large-scale rainfall induced debris flow disasters,with large damage and stronger wallop,will easily occur in the 5-10 year after earthquake.If considering to use directly the debris flow deposit in the main gully of Niumiangou va... |
