韩城电厂滑坡于1990年和1995年先后经过了两次治理。为了检验综合治理效果,观测山体变形滑移、厂区变形活动规律,于1996年底建立了滑坡深部变形监测体系,采用激光准直系统、三向测缝计、钻孔测斜仪等多种方法对韩城电场滑坡进行了长期的深部变形监测,获得了滑坡多年的深部位移数据。监测成果表明:滑坡存在指向SW的蠕滑变形,但各监测点位移变化处于较低水平,山体和厂区无明显的异常变形现象。滑坡综合治理效果明显,保证了电厂的安全运营。
Hancheng power plant landslide in 1990 and 1995 has gone through two treatment. In order to test the effect of comprehensive control, observing the deformation and slip of the mountain and the law of deformation in the plant area, a deep landslide deformation monitoring system was established at the end of 1996. A variety of methods such as laser collimation system, three-way seam measurement and borehole inclinometer Hancheng electric field landslide long-term deep deformation monitoring, obtained many years of deep displacement of the landslide data. The monitoring results show that there is a creep deformation of the landslide pointing to the SW, but the displacement of each monitoring point is at a low level, and there is no obvious abnormal deformation in the mountain and the factory. Landslide comprehensive treatment effect is obvious, to ensure the safe operation of power plants.
