Abstract:

Taking the construction of No.1 and No.2 inclined shafts and main body of Xingwangmao tunnel on SJSV bid section of TaiyuanZhongwei double track railway located in fully/heavilyweathered waterrich sandstone and waterbearing sand stratum as an example, the authors present the construction technology for the rapid tunneling in fully/heavilyweathered waterrich sandstone and waterbearing sand stratum, after analyzing the traditional construction technology under the specific geological conditions. The authors recommend the rapid tunneling concept, which consists of strengthening the management details, increasing labor forces, making full use of existing equipment, executing parallel construction by developing multiple working faces, making full use of various resources and minimizing construction cycle time. Finally, they present the social and economic benefits of rapid, safe and high efficient construction.
