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。
Man-made geological disasters brought by the production of human society have become very prominent. Human-induced geological disasters are mainly caused by human activities that change the Earth, including changes in the physical structure and chemical environment of the crust and lithosphere beneath the earth’s surface and below, and the combined effect of the two. The change of rock structure easily lead to the concentration of geostress. The concentration of geo-stress and reaching the rock burst strength limit will cause the rock to rupture, thus inducing geological disasters. In human production activities, the destruction of the original rock structure in the natural world by mining and road construction is particularly significant. The article mainly discusses the main mechanism of artificial geological disasters caused by the change of the physical structure of the crust caused by mining and transportation construction. Therefore, in the construction of geological teaching process, we should pay attention to its significance and importance, to stimulate students interest in learning.
