超前小导管施工对暗挖电力隧道施工的数值模拟

The numerical simulation of advance ductule construction to the electric power tunnel construction

太阳宫暗挖电力隧道工程，采用施做超前小导管的方法加固上部围岩．并通过数值模拟分析超前小导管的加固效果，总结了施做超前小导管时主要的控制冈素。

This article in view of the Tai Yang gong digging electric power tunneling, Unit uses advance ductule method reinforcement the upside adjacent formation, and analysis ductule＇s reinforcement effect through the numerical simulation, at the end, summarizes the main controlling factor of makeing advance ductule.
