| Summary: | 碩士 === 國立臺灣海洋大學 === 河海工程學系 === 96 === This research is to scrutinize the most hazardous sections when shielded tunneling machines are applied in MRT constructions、namely、the parts from the start of excavations with shielded tunneling machines to the removal of mirror faces. Referring to the construction environments of MRT in Taipei metropolitan areas、auxiliary methods have been extensively applied in tunnel penetrations though、information about how and what auxiliary methods are chosen for practical applications is little established. Thus、this research is involved with the comparisons of auxiliary methods、so as to offer references for follow-up construction methods in the future. This research confers to several roughly considerable factors、as the understanding of the various factors would result in the integrity of the constructions with auxiliary methods. This research also specifies the principles of methods、the construction machines and tools、the construction processes、and the construction flow path of the six auxiliary methods、and each of which is illustrated with a practical construction case. Besides、this research integrating various construction techniques indicates the characteristics of construction methods、geology adaptable、modified lengths、pile diameters、hardening materials、time limits、and costs of each auxiliary method. According to the findings and the results of this research、it is believed that auxiliary methods for the removals of mirror faces vary from each other、and that collocations of methods are suggested to meet multiple considerations.
