With the increase of traffic pressure in China, the subway has become the main mode of travel to relieve traffic pressure. At present, the construction of the subway has entered a peak period, but the quality problems of the tunnel has also come one after another. The shield method has already dominated the tunnel construction methods. In the shield tunneling, the quality of the entire life cycle of the segment directly determines the quality of the entire tunnel project. At present, the segment detection technology adopts the method of manual work, there are problems such as slow information processing and information sharing troubles. How to use information technology to realize integrated management of detection information has become a trend. Firstly, this article analyzes the inspection information at each stage of the segment. Then, based on the IFC standard model system, expansion methods and graphic representation methods, the segment detection information was expressed and extended, and a segment detection information model based on the IFC standard was established.

Shield method construction. as a kind of safe and effective method of tunnel construction. plays a positive role in the construction of urban rail transit in our country. However, an interval, including partial hard rock section. iS difficult for shield tunneling machine to push forward. When the hard rock drivage reaches a certain length. we usually use "shield law" + "mines" composite construction method. Although this method can improve the construction speed and reduce the construction risk, but also causes many problems. According to the actual situation of Wuhan subway construction, this paper introduces the key technologies and quality control measures of shield to shield, shield advance and receiving phase with good results in the weathered mudstone formation of the hollow push mining method in tunnel construction, providing a useful reference for similar projects.
