摘要
采用传统的加载力学方法和卸荷力学方法,利用数值计算对紫坪铺水利工程引水发电隧洞进口高边坡开挖后的应力-应变进行了研究。对比分析两种计算方式算得的边坡位移成果,揭示了岩体开挖边坡的卸荷变形及加固效应特性。
For the high slope of intake of diversion tunnel of Zipingpu Irrigation Project, the relationships of stress and strain are calculated by traditional mechanical methods of unloading and loading. The results on slope displacement calculated by the two methods of loading and unloading are compared, and the excavation unloading-induced deformation and corresponding support for the slope are shown.
