摘　　要：人类社会生产带来的人为地质灾害已十分突出,人为地质灾害主要起因于人类活动对地球的改变,包括地表及其以下的地壳岩石圈的物理结构和化学环境的改变以及两者的联合作用。岩石结构的改变容易导致地应力的集中,地应力集中并达到岩石破裂强度极限就会导致岩石破裂,从而诱发地质灾害。在人类的生产活动中,矿山开采和道路建设对自然界原始岩石结构的破坏作用尤为显著,文章主要就矿山开采和交通建设造成地壳物理结构改变所引起人为地质灾害的主要机理进行简单探讨。因此在构造地质教学过程中,应该重视其意义和重要性,激发学生的学习兴趣。The hazard of the geologic disaster induced by human activity is more and more prominent. The induced geologic disasters are mainly caused by the spoiling and destruction of the rock structure and the natural geological chemical environment. The spoiling and destruction of the rock structure probably lead the concentration of the tectonic stress, which make the rock to break out easily and thus the induced geologic disaster take place. Among all the construction by human, the structure of crustal rock is especially easy to be destructed during the mining and road construction. Therefore, this paper focuses on the discussion on the mechanism and hazard of the induced geologic disaster during mining and road construction process. Thus, its important and significant to stimulate the interests of students in the relationship between the structural geology and the induced geologic disaster.
