三峡库区移民工程建设地质工作评介

An introduction to geologic work for resettlement construction in TGP reservoir area

三峡库区城镇迁建之初，由于没有充分考虑到选址的地质问题，以致产生新的地质灾害，诸如边坡失稳、滑坡复活、道路坍陷等。针对此类问题，长江委在库区各县设立了地质工作站。地质工作站的工作内容和目的就是为迁建城镇、居民点的选址提供地质资料，当好地质参谋。具体的作法是针对各县市在迁建实施过程中所遇到的各种地质问题进行补充察勘，并根据实际情况科学地预测将产生的工程地质问题，并提出处理建议及防治措施。从几年的工作实践看，地质工作站的成绩是显著的，这一做法对指导今后大型水利工程的移民工程建设具有借鉴意义。

At the beginning of city and town relegation in TGP reservoir area, as the geologic conditions for site selection were not fully considered, some new geologic accidents such as slope failure, reviVal of landslide, and road collapse etc.occurred. Thus, the Changjiang Water Resources Commission has set up geologic work stations in counties of TGP reservoirarea. The taSk of the geologic work stations is to offer geologic data and consultative service for site selection of relocatedcity, town and residential quarter. According to various geologic problems encountered in the course of relocation, these stations conduct suPPlemental geologic investigation, predict Possibly occurring engineering geology problems, and put forward corresponding treatment suggestions and control measures. Since the set up of the geologic work stations, the achievementshave been remarkable, and the practice might be refelable for guiding resettlement construction of other large scale waterconservancy projectS.
