论安口滑坡的形成、发展及演变特征

FORMATION,DEVELOPMENT AND EVOLUTION CHARACTERISTICS OF THE ANKOU LANDSLIDE

本文主要介绍沟口洪积扇型堆积层滑坡——安口滑坡的地质、勘测设计、施工整治概况及效果。以大量的勘探资料和施工清方暴露出的实际情况为依据，论述安口滑坡的形成、发展演变历史、类型及特征。从工程地质角度，对在沟口洪积扇型堆积层滑坡地段选线、重大建筑物的选址及此类滑坡的勘测设计，提出需要重点注意的一些问题。

The Ankou landslide is a diluvial fan deposit landsilde at the entrance of a gully.Its geology,survey and design,countermeasures during construction and their effects are mainly introduced in this paper.Based on the plenty surveying informations and the practical situations revealed by removal cut during construction,the formation,devoloping and evolutional history,style and characteristic of the Ankou landslide are explored in detail.From the viewpoint of geotechnology,concerned with the route selection and the disposition of important buildings on the section of a diluvial fan deposit landslide at the entrance of the gully,as well as the survey and design of this kind of landslide,several problems which we must pay special attention are proposed。
