水库蓄水及运行过程中,岸坡所处的地质环境将发生显著改变,河道发生壅水,水位抬高,水深加大,水面变宽,浪蚀作用加剧,破坏了原来河谷岸坡的自然平衡条件,从而引起岸坡稳定性的变化并产生库岸再造。巫山新县城一带库岸冲沟发育,岸线弯曲,地质条件复杂。三峡水库蓄水后再造强烈及不稳定库岸长达5.38km。根据不同的岩层、岩性特征和库岸再造类型及防护对象综合确定防护措施。
During the process of reservoir water storage and operation, the geological environment of the bank will change significantly. The waterway rises, the water level rises, the water depth increases, the water surface widens and the erosion effect aggravates, thus destroying the nature of the original valley bank Balance the conditions, causing changes in the stability of the bank and the resulting reservoir bank reconstruction. Wushan new county along the bank gully development, coastline bending, complex geological conditions. The Three Gorges Reservoir rebuilds strong and unstable reservoir impoundment up to 5.38km. According to different rock formations, lithology characteristics and the type of bank and bank reconstruction and protection of objects to determine comprehensive protective measures.
