| 摘 要： | 理县医院后山滑坡为＂5.12汶川地震＂诱发的次生地质灾害。地震导致医院后山斜坡开裂,形成三级主裂缝,降低了斜坡稳定性,形成次生滑坡灾害,后期降雨及余震则使滑坡继续变形发展。为及时掌握滑坡的变形趋势,做好防灾准备,同时为后续治理工程提供依据,开展了以裂缝位移监测为主的应急阶段自动化监测工作。监测系统由裂缝位移计、无线数传终端、太阳能供电组件以及室内计算机、监测管理软件组成。根据理县医院后山滑坡具备三级主裂缝的特点,在每级裂缝上沿走向设置监测点,共设置9个,各监测点每小时自动巡检一次。

| Abstract: | The landslide at the back of the hospital in Lixian is the secondary geology disaster after"5.12 Wenchuan earthquakes".The earthquake causes the mountain at the back of the hospital to crack,form third-level main crack and reduce the slope stability to forming the secondary landslide disaster.Later rainfall and the aftershock causes the landslide to deform continuously.To prevent the landslide disaster,and provide basis for the following treatment engineering of the landslide,it is necessary to conduct emergency automatic monitoring,specially for crack displacement monitoring.The observation system consists of crack displacement meter,wireless data transfer terminal solar energy supply device,indoor computer and the monitoring management software.According to the landslide at the back of the hospital in Lixian which has the characteristic of the third-level main crack,nine monitoring points are set on each crack along the trend.Every monitoring point inspects automatically once per hour. |
