摘要
巫山县城新址位于西坪和大宁河两岸。组成该库段的基岩主要为泥岩、粉砂岩、泥灰岩等,岩性较软弱,且地质构造变动强烈,褶皱、断裂发育,岩层破碎,崩塌、滑坡分布较多,库岸再造问题严重;同时,岸坡再造又严重影响着新县城的规划和库岸的防护。因此把稳态坡形类比法应用于巫山县城新址基岩岸坡的再造预测,定量预测库岸的最终再造宽度,以指导新城的规划与建设。
Wushan County is one of the flooded cities in the Three Gorges Reservoir region, and its new site lies in Xiping and two banks of Daning River. The reservoir bank mainly composed of shale, fine sandstone and shale limestone etc are weak. Because of the violent geologic tectonic movement, the rich fold and fracture, the cracked rock, and the frequently-occurring falling and landslide, the bank rebuilding will be very severe and badly effect the scheme and reservoir bank＇s protection of the new county site. This paper uses the analogy method of stable bank to predict the rocky bank rebuilding of the new site of Wushan County and shows that the rebuilding width can be used to direct its scheme and construction.
