    Abstract: 摘要
    The use of shield tunnel has been in practice for a long time and has matured since its introduction into Taiwan. A shield tunnel is contracted for construction after the geological survey and drawing of the design. The construction contractor must analyze the data based on the geological survey information and supplementary geological reports, excavation path, ground water elevation, covering depth, radius of curvature, the outer diameter of tunnel boring machine and other factors and conditions and discuss with the manufacturer to determine the tunnel boring machine suitable for the geological conditions of this project.

    The selection and design of the shield machine and the planning and simulation works before the construction can lead to the success of the shield tunnel project or when one of the key factors and process are ignored due to cost consideration may lead to the delay or stop of the work which result in disasters, remedies are sought with tremendous costs incurred to find solutions. Using the actual construction cases, this paper explores and analyzes the issues to be noted and the construction difficulties encountered due to ignorance of the precaution measures as well as the solutions to the issues on the construction site based on the difficulties encountered and the process of the excavation by the tunnel boring machines which may encounter obstacles and have delays in their advances. It is hoped that the insights gained will serve as reference for study and analysis by those who are interested in the design and construction of shield tunnels.
