资源枯竭型城市的地质环境治理研究——以云南东川为例

摘要

通过近1年的调查研究,获取了东川区深沟、尼拉姑沟、大桥河沟、田坝干沟、腊利河沟5条对城区危害最为严重的泥石流沟地质环境的详细资料及数据,概述了5条泥石流沟的情况,分析了该区域的地层岩性、地质构造与地震、水文地质条件、不良地质现象,根据不同实际情况提出了不同治理方案.%Based on the investigation and research in the past one year, the detailed information and data of geological environment of the debris flow gullies which are the most serious harm to the city, including Shen gully, Nilagu gully, Daqiaohe gully, Tianba gully and Lali gul-ly, were obtained.The general situation of the above debris flow gullies were reviewed, formation lithology, geological structure and earth-quake, hydrogeological condition, bad geological phenomenon in Dongchuan District were analyzed.According to the actual situation, differ-ent control schemes were proposed.
