摘要

近年来,极端天气不断增加,陕北地区接连发生伤亡性地质灾害,尤以崩塌灾害发生前兆不明显,一旦发生致灾后果严重。神木县是陕北地区的经济第一强县,地质环境条件复杂多样,受人类工程活动影响严重,崩塌灾害占到全县地质灾害总数的76%,发育极为典型。本文依托"陕西省榆林市神木县地质灾害详细调查"项目,通过对调查资料分析得出,神木县崩塌灾害多发生在丘陵和河谷阶地地貌单元内大于60°的坡体上,坡向以S、SW、W为主,坡高多小于60m,厚度为3m、5m,坡宽在10-200m之间,斜坡岩土体类型多为岩体单层结构;而发生时间与常规认识有所差异,并非仅在汛期而是全年易发。最后提出加强重点宣传培训,以预防为主的防治对策,以期进而为陕北地区的的减灾防灾工作提供一定参考。
In recent years, with increasing incidence of extreme weather, spate of injuries often happen in Northern Shaanxi.Among these geological disasters, the collapse disasters precursor is not obvious. In case of occuring serious disasters,it will become the most terrible consequence. Economy of Shenmu county in northern Shaanxi is the first place.It has complex and varied geological environment condition, also affected by human engineering activities. Collapse disasters account for 76% of the total number of the county geological disasters. It is very typical. "Shenmu county, yulin city of shaanxi province in this paper, based on detailed investigation of geological disasters" project and the survey data analysis to get the result that collapse occurred more in shenmu county in hilly and valley terraces geomorphic unit greater than the slope of 60°.The slope's direction is given priority to S, SW and W,and most of them is less than 60 m, thickness is 3 m to 5 m,slope is between 30 m to200m wide.Mostly single junction of rock mass slope rock mass types.When it appear,it mybe missunderstand with our common sense.lt not only in the flood season but is used throughout the year. Finally, to highlight the publicity and training prevention countermeasures, in order to prevent further for the work of disaster and reduction of northern Shaanxi,this paper will provide certain reference.
