Abstract

In order to analyze the construction efficiency of shield machine and improve accuracy of calculating the unit price of shield machine construction,based on the practical condition and related data,and further according to the basic principle of control chart,the reasonable upper controlling line and lower controlling line were set up to filter out the abnormal data.The construction efficiencies of shield machine construction in different geological conditions and cases were analyzed tentatively.Therefore,the basic data and related experiences were provided for correctly predicting and controlling the investment of similar works.
