摘要
通过溪洛渡地区1∶2.5万区域地质调查获得的第一手系统资料的综合分析,论述区内地质灾害事件所形成的第四系(本文简称灾害第四系)——滑坡堆积、堵江堰塞堆积和泥石流堆积的特征,首次确认区内堵江堰塞堆积的存在,并结合工程实际对灾害第四系的稳定性进行评价。
The Quaternary formed by disastrous events (called as disastrous Quaternary)is quite different from the common one such as laucustrine sediments,and is generally dangerous to the engineering activities.The disastrous Quaternary such as landslide accumulation is well developed in Xiluodu region,the present paper introduces the characteristics of landslides,debris flow and natural damming lake accumulation and delta sediment.The existence of the natural damming accumulation is identified.The evaluation of the stability of the accumulation is also given in the paper.
