摘要
采用遥感解译与工程地质测量相结合的方法,开展了雅江县城地质灾害发育特征调查以及单体地质灾害稳定性和发展趋势预测,提出了防治对策建议。研究表明:雅江县城共发育7处地质灾害隐患点,威胁83户城镇居民的生命财产安全以及G318国道、雅江中学的安全运行;地质灾害体稳定性均处于差和较差级别,滑坡和危岩崩塌为雅江县城最主要危险源;雅江县城地质灾害防治应遵循"工程治理为主,专业监测与群测群防相结合"的原则,系统开展应急排危工程、综合治理工程和专业监测工程,最大限度消除地质灾害隐患,为雅江县城建设和发展提供地质安全保障。
Based on RS interpretation and field surveying, both investigation and assessment on geological hazards in Yajiang city have been carried out. Four conclusions are drawn as follows. Seven geological hazards have been checked out in Yajiang city, including 1 debris flow, 3 landslides, 2 potential unstable slopes and 1 dangerous rockmass. The safety of residents from 83 families and operation of G318 national highway and Ya- jiang middle school are threatened by these geo-hazards. Stability assessment indicates that all geo-hazards are at unstable condition. Landslide and rock collapse consist of the main hazard source in Yajiang city. As far as the principle of geo-hazard prevention in Yajiang city, priority should be given to engineering control and profes- sional monitoring measures. Finally, corresponding prevention suggestions were brought forward in detail for ev- ery geological hazard. The study can provide geological reference both for geo-hazard prevention and for the con- struction and development of Yajiang city.
