分析了德兴铜矿１８５ｍ水平中段陷落区的工程地质特征，并划分了岩体结构类型和工程地质分区；选择了五个代表性剖面进行有限元数值模拟分析，最后对陷落区的公路作了稳定性评价．
The engineering geological features of the 185m middle-level depression area in Dexing Copper Mine are analyzed and the rock mass structure type and engineering geological division are divided. Five representative sections are selected for numerical simulation analysis. Finally, the highway in the subsidence area is made Stability evaluation.
