STUDY ON APPLICATION OF REMOTE SENSING TO REGIONAL STABILITY AND SITING OF THE ANQING OF HIGHWAY BRIDGE ACROSS CHANGJIANG RIVER

Geological Remote Sensing Center of Anhui Province, Hefei 230001

摘要

摘要: 安庆长江公路大桥区域稳定性及预选桥位线方案是大桥建设前期的一项重要基础性工作。本文是利用航、卫片地质解译调查 ,分析研究拟选桥址区及其外围的地质构造特征 ,新、老断层的分布情况及其活动性 ,并进行区域稳定性评价 ;利用5 0至 90年代的航、卫片资料 ,分析评价了拟选桥址区长江岸带变迁及稳定性 ;对预选桥址区工程地质条件及优选桥位线方案进行比较与论证。

Abstract: Study of the regional stability and preliminary siting of the Anqing bridge are the important, basic work prior to the construction of the bridge. According to the requirements of the preliminary feasibility research, a study of remote sensing application aims to do the following works: (1) analysis of the alternative areas of the preliminary bridge site and the characteristics of its surrounding geological structures, understanding distribution of old and young faults in the area and analysis of their activity and evaluation ofthe regional stability by means of geological interpretation of the aerial and Landsat images; (2) analysis of evolution of the Changjiang River banks in the possible bridge site area and evaluation of its stability by using the aerial and Landsat images taken from 1950s to 1990s; and (3) analysis of engineering geological conditions of the preliminarily sited bridge areas, and put forward an optimum scheme.
