四川省南充市城区斜坡工程地质问题及防治对策研究

Study on the engineering geological problems of slope and their prevention countermeasures in Nanchong City,Sichuan province

南充市为嘉陵江流域的大型城市之一。其主要工矿企业及城市发展的重点均位于嘉陵江Ⅲ级阶地。该阶地为南充市斜坡工程地质问题主要发育场所。为此查明南充市区斜坡工程地质条件,对其发展有着重要意义。文章根据多年积累的大量实际资料分析研究,总结了南充市区的主要斜坡工程地质灾害类型为滑坡、崩塌及岸坡失稳。其中以滑坡最为常见;影响斜坡工程地质问题产生的主要因素为岩土性质、风化作用和水的作用;针对不同的斜坡工程地质问题,提出了具体的工程防治对策。

Nanchong ci developments are aroun ty is one of the largest cities along Jialin River. Most industry, mining enterprises and new d the third terrace of the river, so that many engineering geological problems were occurred at the areas. In this paper, the authors classify the problems into landslide, rockfall and collapse of river bank, and relevant influence factors, for example, geo-material properties, weathering and surface/ground water, and finally suggest some control measurements.
