摘要
重庆地区属红层分布区,经常遇到紫红色、灰色泥岩与杂色砂岩组成的层状岩体斜坡或软弱基座斜坡,为全国滑坡灾害严重的地区之一。文章以重庆涪陵区谷水溪滑坡监测为例,对裂缝观测法在滑坡监测中的应用做了探讨。通过布设裂缝观测标志,按监测周期采集数据,对裂缝观测数据进行统计分析,并成功地做出预警预报,使100余人安全撤离;减少财产损失1500余万元,运用裂缝观测法监测滑坡收到了较好的效果。裂缝观测法是地质灾害群测群防中一种有效的基础方法。
Chongqing region belonging to the red beds area, distributes many bedded slopes or weak foundation slopes constituted with the red or gray mudstone and mottled sandstone, which is one of the most serious landslide hazard regions in the country. This paper discusses on the application of the method of crack observation in landslide monitoring, Gushuixi Iandslide in Fuling District, Chongqing at the example. The crack marks are established, and the data is collected according to the monitoring period. Based on the analysis of the crack monitoring data and a period of effective monitoring, an early warning was done successfully. More than 100 people withdrawn safely and the loss of properties was decreased for more than 15 millions yuan. The good result is received because of the application of crack observation method in landslide monitoring. The crack observation method is an effective and basic method for geological disaster monitoring and warning for public prevention.
