中文摘要 | 由于形成山地灾害的多种自然因素具有垂直地带性,尤其作为主要动力因素的水,超过一定高度后由液态成为固态,从而造成了山地灾害的垂直地带性。山地灾害从高到低可分为冰雪带、冻融带和流水(古地下水,裂隙水)带,高低两带之间主体界线在南水北调西线工程及其邻近地区为4900m和3500m。各带均有其特点,其中对西线第一期工程及其下游地区可能造成重大影响的有:大型的冰崩、雪崩、冰湖崩决、滑坡或古滑坡复活、泥石流、泥石流坝或滑坡坝溃决。但这些大型山地灾害在该地区不很严重.今后出现的可能性小,只要引起重视,妥善处理,可以避免或减轻其危害。 |
英文摘要 | Because the vertical zonality of many natural factors which cause mountain hazards.water in particular,as a main dynamic factor when the height outweigh a certain elevation will change from liquid state tO solidity,which induce the vertical zonality of mountain hazards.From the higher levels to the low— er levels,ice and snow zone,freezing—melting zone and running water zone (including groundwater and crevice water)could be divided.The main body limits between two neighboring zones are 4900 meters and 3500 meters in the western route of South—to—North Water Transfer Project and its neighborhood.There are many especial mountain hazards in every zone where large ice avalanche,avalanche,ice lake—break, landslide or fossil landslide reviving,debris—flow dam outburst or landslide dam outburst would cause great effects on the first western route of South—to—North Water Transfer Project and its neighboring regions. But these great mountain hazards are not serious in these regions,and the possibility of mountain hazards is low.If we pay more attention to them and take careful and skillful handling measures,the hazards would be avoided or reduced. |
