摘要
三峡水库自 2 0 0 3年蓄水后 ,水对斜坡 (滑坡 )的软化作用和库岸再造大大改变了库区的工程地质条件 ,库区的地质灾害严重制约了库区移民迁镇工程 ,场地建筑安全评价显得尤为重要。笔者根据库区工程地质的特点 ,提出了场地建筑适宜性评价的指标体系 ,建立了场地建筑安全评价人工神经网络模型。通过对红石包滑坡进行各种工况下的稳定性评价 ,利用稳态坡形、坡角工程地质类比法对红石包进行库岸再造的预测 ,对三峡库区巴东县新城区红石包油库建筑进行安全评价。为库区移民迁镇工作提供科学依据。
Being intenerated by water at slope (landslide) and bank rebuilding changed greatly the engineering geological condition in Three Gorges reservoir region since the reservoir began to store in 2003. The geological disasters in Three Gorges reservoir region severely restricted the immigration and construction engineering. So safety evaluation for site building became very important. Based on the characteristic of engineering geology of the reservoir region, the index system for feasibility evaluation of site building in Three Gorges region was established. Artificial neural network model for safety evaluation of site building was set. Stability evaluation of landslides and the prediction of bank rebuilding by stable side shape and geological analog method for slope were applied to the safety evaluation of Hongshibao oil depot in new city of Badong County, which might provide scientific criteria for immigration and city rebuilding.
