半岭滑坡及掩树坑泥石流的致灾机理探讨

Landslide and debris flow Disaster-causing mechanism in Semi-Ling and YanShuKeng villages

本文通过对半岭滑坡、掩树坑泥石流的形成机理及主要影响因素的分析,提出了是否及时发现地质灾害前兆是预防地质灾害发生的关键等观点,对存在灾害隐患的山区自然村,特别是存在较大临空面,具备形成高势能滑坡的地质灾害隐患点,有计划的实施灾前搬迁比灾后安置,不仅可以节约对灾害隐患点监测时所需的大量人力物力,其成效也将更加显著。

According to the analysis of formation mecjanism and influencing factors of Semi--Ling landslide and YanShuKeng debris flow, whether timely detection of a precursor to geological disasters is the key to the prevention of geological diasasters is presented in this paper. To the mountain villages where existing disaster risks, especially the landslide which existing a big free face and have high potential energy, the relocation of pre-- disaster and post--disater resettlement are well planned. Through these, not only can save a large number of human and material resources in moni- toring the disaster, its effectiveness will also be more significant.
