摘要
我国约有160多个城市发生不同程度的地质灾害,迫切需要查明其成因,估计其发展趋势,并提出减小灾害的方法。本文以铜陵市长江路大面积出现的地裂缝及塌陷为例,对比使用了电法、磁法、地质钻探、人工地震等方法。认为人工地震方法在喀斯特地区可以用来确定此类地质灾害的范围、趋势和找出其成因。
Taking ground fissures and collapse in the Toling city of Anhui province and through comparison of geophysical exploration measures, such as electrical sounding, magnetic prospecting, geological drilling and shallow seismic sounding, it is concluded that the shallow seismic sounding can determine the scope, tendency and origin of the geological disasters in Karst areas.
