长白山旅游区崩滑形成影响因素研究

Research on influence factors of collapse-slide in tourist area of Changbai Mountain

崩滑是长白山旅游区地质灾害类型之一。通过分析发现,影响该区崩滑形成的因素有区域地质构造、地层岩性、地形地貌及气象水文条件。同时,结合该区域内斜坡体的现状,总结了影响崩滑这种地质灾害发生的内因有区域构造、地层岩性、地形地貌,外因有气象条件、水的作用、冻融及外动力作用。崩滑灾害的发生是内外因相互作用的结果,并提出了崩滑灾害发生具有时间规律,对崩滑类地质灾害可采用疏水、挂网与封闭裂隙相结合的综合治理方法。

Collapse-slide is a disaster in Changbai Mountain tourist area. The influence factors of collapse-slide are regional tectonic, stratum lithologic,geomorphic,meteorological and hydrographic characteristics of Changbai Mountain. Based on the present state of slope, the influence factors of collapse-slide are summarized as follows: internal factors ?regional tectonic,geomorphic and stratum lithologic characteristics and external factors ?hydration,weather,freezing, melting. Both internal and external factors cause the collapse-slide. In this paper, the regularity of collapse-slide disarster is presented and it suggests dredging, hitching and blocking out cranny as control methods.
