摘要
崩岸是长江汛期大堤最严重险情。 1998年长江特大洪水后期 ,宜都河段茶店岸坡崩岸直接威胁长江大堤安全。本文分析了长江宜都河段的环境地质条件 ,宜都河段河流地质作用的基本特征。系统研究了茶店崩岸的形成机制及稳定性分析 ,最后提出了岸坡崩岸防治措施。
Embankment collapse is a heavy hazard for Changjiang River during flood season. The Chadian embankment collapse occurred at Yidu Reach of Changjiang River during the flood period 1998. The environmental geological conditions of the Yidu Reach are analyzed in the paper. The formation mechanism and stability of the embankment collapse are studied systematically. The control measures for the Chadian embankment collapse at Yidu Reach are presented.
