程潮铁矿截排洪隧洞支护优化研究

Optimization study on closure-drainage tunnel support in Chengchao iron mine

结合武钢程潮铁矿矿区截排洪续建工程,运用岩土数值分析软件对各类围岩条件下隧洞开挖及支护结构进行数值模拟。并确定隧洞合理的开挖与最优的支护方案。在保证隧洞安全的前提条件下,合理地进行支护设计与施工,尽量节约工程造价和工程投资,保证截排洪工程尽早完成。

As closure-drainage tunnel in Chengchao iron-mine taken into consideration, FLAC is used to simulate the rock tunnel excavation and support under the conditions of the various wall rock types. As a result, reasonable tunnel excavation plan and the best support scheme are determined. To ensure the construction safety and period, reasonable support is designed and constructed, and the project cost is saved.
