The management mode of scientific researchdesignconstruction integration is adopted in Line No. 4 project of Ningbo Metro; and the technical system of railway transit quasirectangular shield tunnel is developed. By adopting the abovementioned technical system, the problems of segment design and structural optimization have been solved. The fullface cutterhead and driving system, shield hinging and sealing technology and ringarm segment erector have been developed. The simultaneous grouting technology, segment erection simulation and technical optimization and shield axial line control have been studied. A new kind of singletube doubleline tunnel will appear to solve the problem of limit underground space in core districts of cities in China.
