Abstract:

There are many difficulties in the construction of long tunnels by access from inclined shafts. The transportation system in the inclined shafts (particularly the construction material supply through inclined shafts), the equipment type selection, water pumping and organization of construction activities at multiple working faces have great influence on the construction schedule and safety management. Taking the construction of Xiangshan tunnel on LongyanXiamen railway in Fujian province as an example, the author summarizes the experience in inclined shaft crosssection selection, transportation system determination and transportation capacity evaluation in this paper. The construction practice shows that reasonable inclined shaft crosssections, rationallymatched equipment, scientific design of muck tanks at inclined shaft bottoms and improving the construction material supply capacity by taking assistant measures can accelerate the construction speed of these tunnels.

Key words: inclined shaft with track transportation system, cross section, transportation capacity, muck tank
