泰山风景名胜区崩塌灾害现状及防治对策

Present Condition and Origin of Collapse Hazards and Its Prevention Countermeasures in Taishan Mountain Scenery Area

摘要:

泰山风景名胜区崩塌灾害较多,主要在中低山区及丘陵区的公路切坡段,以小二型为主,次为小一型,已造成较大经济损失和人员伤亡。崩塌的形成取决于构造、地形条件,受暴风雨、地震、人类活动等因素影响,构造复合部位的陡崖更易发生崩塌。崩塌产生的内因是陡峭山体中存在结构面外倾的岩体或块石,外因是暴雨等外力活动的诱发,内外因在特定条件下的结合是易发区内崩塌产生的主要原因。根据崩塌隐患区的不同特征,可分别采取锚固、注浆、平垌、生态工程、避让等措施防治。
