| 摘 要： | 水工隧洞洞径大,地质构造复杂,因其地质背景和岩体各种特性参数不准确,理论计算难以准确掌握其工作状态,尤其在施工期还受到施工过程的扰动.原型监测是监控其工作状态的有效手段.文中以某电站地下厂房进水隧洞为例,根据现场监测资料,通过建立回归模型,分析、预测隧洞围岩体的变化规律,并探讨了围岩体的空间变形分布情况.分析结果表明隧洞围岩体目前是稳定的.

| Abstract: | The diameter of hydraulic tunnels is large,and their geological structure is complex.The parameters of geological background and rock properties are inaccurate.The theoretical calculations cannot precisely reflect their work states,especially during their construction they are disturbed by the construction process.The prototype observation is an effective way to monitor their work states.Based on the water transfer tunnel of underground powerhouse of a hydropower station,a regression model was established t... |
