摘要
2021年7月20日郑州城市遭遇百年未遇的特大洪灾,地铁被淹、严重内涝、城市路面在洪水中长期浸泡,导致局部地段塌陷严重,给人们的生产生活带来极大的安全隐患。要对塌陷区进行有效治理,关键是了解塌陷区的位置、埋深、规模、围岩状况、应力状态等要素,本次研究主要利用先进的物探技术手段——高密度电法,对河南工业大学地铁站附近塌陷区进行勘测,对异常塌陷位置进行精确定位,为后期塌陷区处理提供必要的依据,研究成果可为城市塌陷区治理提供借鉴。
7.20 The city of Zhengzhou suffered a severe flood that had never happened in a century. The subway was flooded and the urban road surface was soaked in the flood for a long time, which led to the serious collapse of some sections and brought great safety risks to people’s production and life. This topic mainly uses the advanced geophysical exploration technology means high-density electrical method to survey the subsidence area near the subway station of Henan University of Technology, accurately locate the abnormal subsidence location, and provide the necessary basis for the later subsidence area treatment. In order to effectively control the subsidence area, the key is to understand the location, buried depth, scale, surrounding rock condition, stress state and other factors of the subsidence area. Only when the spatial distribution state of the subsidence area is fully understood, the control can have a definite target.
