摘　　要：以宜昌市黄家湾垃圾处理场排洪洞为例 ,介绍了锚喷网支护技术在浅埋软弱围岩隧洞施工中的应用 ,并通过监测 ,表明锚喷网支护能最大限度地发挥围岩的自承能力、变被动支护为主动支护 。This text handles a tunnel for draining off water in Huangjiawangarbage ground,in YichangCities is for the example, introducedthe support techniqueofthe anchored bar, thesprayed concrete associated withthereinforcement matwhich is used in theengineeringconstruction, and pass to monitor, express the support technique can develop to the maximum bearing, and become the passive support becomean active support , so the the support technique guarantees the stabilizationof the tunnel and the normal proceeding of theconstruction with theengineering.
