Abstract
The risk for shield tunneling construction projects are the unknown underground conditions such as the ground water, rocks, woods and the pernicious gases. When the shielded tunnel boring machines tunnel forward, the ground improvement does certainty or not the operation statistics such as driving power, driving speed, chamber pressure, soil discharge rate, the lining and back filled grouting will influence the result mostly. How to analyze and estimate the risk in advance and make the strategy to prevent it for shield tunneling construction projects are the main purpose for this research.
In this research, the main purpose is to establish the measuring method to improve the productivity and management on schedule, cost and quality. In order to get enough data, it chooses the site efficiency measurement method, interviewing method and experience observation method. Besides, There is also the methods to help this research to reach the purpose.
This research collect 12 shield tunneling cases in Taipei city。 The project cost ranges from 100 million to 800 million N.T. dollars. To analyze the impact factors of productivity, we get the factors such as the ground condition, machine, underground obstacle, excavation management, neighborhood building monitoring, the conclusions and suggestions could provide a method to improve the management and also could save the cost, reduce the risks and make the project time target be easier reached.
