摘要
四川汶川"5.12"地震后,构造剥蚀中低山、丘陵区的山谷斜坡上,形成了大量的崩塌、滑坡、泥石流等次生地质灾害变形体。这些地段多分布有重要的工程建筑、村庄、城镇人口密集区,地震波效应后的松散岩土体,在降雨、外力等作用下,稳定性迅速降低。灾后防治工程一定要在分析变形体所处地质环境、变形历史、现状变形特征及演化趋势规律的条件下,提出经济科学、合理的防灾、减灾对策及治理方案。
After Wenehuan "5. 12"earthquake of Siehuan province, there are many secondary geological disasters such as tallings,slides and mudrock flows in denudation hill areas valley in low mountain slopes, there are many important projects, villages and densely populated areas. After earthquakes the stability of lase rock and soil mass is decrease sharply with the distroy of rain fall and external. Disaster proveting must aeorrding to the geological environment, deformation history, deformation characties of the status and evolution,give us a economic and scientific, reasonable ways to prevent disasters and decrease disaster and governance programs.
