新滩链子崖地段核桃背大型座滑体初步探讨

PRELIMINARY RESEARCHES ON HETAOBEI LARBE FALL SLIP MASS WITHIN THE SECTOR OF LIANZIYA,XINTAN

本文在1:2000的工程地质测绘的基础上,对核桃背座滑体的形体特征、形成机制、运动形式、稳定程度以及与链子崖危岩体的关系等方面进行了探讨。提出该座滑体的运动形式,为链子崖危岩体变形破坏的分析提供了一种运动形式的借鉴。

Hetaobei fall slip mass is situated to the western side of the top of famous Lianziya dangerous body which locks the Bingshu-Baojian gorge＇s mouth so tight that the shipping of Yangzi River is seriously imperilled; by monitor, Lianziya dangerous body is recently deforming increasingly. In mapping the complementary engineering geology of Lianziya sector on the scale of 1: 2000, Hetaobei fall slip mass was found for the first time. Because it is immediately neighbouring with Lianziya dangerous body and it is of large scale, this body has attracted relevant person＇s attention. The present paper researches on such aspects as morphological characteris—tics, forming mechanism, motion patterns, stability, relationship between Hetaobei fall slip mass and Lianziya dangerous body, etc; and puts forward motion patterns of the mass, by which a motion pattern used for reference is provided for analyzing the deformation and failure of Lianziya danger—ous body.
