摘要
Abstract
Shigu Water Source Project of Central Yunnan Water Diversion Project is located on the left bank of Chongjiang River intake tunnel,in a water rich formation below the mountain's groundwater level,with abundant groundwater volume.The tunnel body passes through unfavorable geological sections such as fault fracture zones,karst fissures(caves),and karst pipelines.Groundwater flows out in the form of strands along the channels such as karst fissures and caves,eroding the filling materials in the channels and forming cavities,which have adverse effects on the stability of the tunnel body and pose safety hazards.The water influx inside the tunnel will also hinder the construction inside,affecting the construction progress and quality.During the tunnel construction process,it is necessary to determine water blocking schemes based on different water inflow situations to ensure construction safety and quality.CIS new material water blocking grouting construction scheme has been adopted,achieving significant results.关键词
