A Research of Economy & Applicability of Metro Shield Station Crossing

With the background of metro construction,two plans of shield station crossing and shield station non-crossing are compared and analyzed on the construction cost and implicit cost.And shield station crossing plan is of advantages on cost(under certain condition) and construction period.The view of shield station crossing adding the width of the station and increasing the cost is refuted by some project case.Moreover,the applicability condition of shield station crossing is analyzed,which is of important realistic significance to speed up metro construction and to lower metro construction cost.
