浅谈地质预报与监测在某水电站边坡塌方中发挥的作用

该洞口进口段及边坡有多条岩脉在此交汇,工程地质条件较差,在开挖过程中由于支护不及时,发生了冒顶,但在冒顶前,多点位移计等监测仪器监测到了不同程度的突变,地质预报也根据开挖情况及时进行预了围岩类别的预测及安全提示,对指导施工及人员安全发挥了预测及提醒作用。

There are many dykes intersecting in the spillway entrance section and the slope,so the geological conditions are poor,the roof fall occurred because of not timely supporting when excavated,but before the roof falled,and more displacement meter and other monitoring equipment monitored the varying degrees of mutation,geological forecasts also timely predicted the type of surrounding rock and safety prediction according to the excavation condition,this played a forecasting and remindering role in instructing construction and personnel safety.
