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.
