Since 1863 London built the worlds first underground railway, subway construction has accumulated more than 130 years of experience and theoretical results so far, the design ofand construction of metro tunnel technology became more and more mature. Chinas subway construction began late. Since the reform and opening up, along with the continuous development of the national economy, our countrys urbanization process is gradually accelerated. Economic development, peoples living standards improve, the expansion of city scale, the rapid increase of urban population, urban traffic facing a grim situation, at this moment, the subway construction to more and more into the peoples vision. The design for the Qingdao City Subway Line 3, Huiquan Square Station No. 3 out of inlet structure design, the use of load structure method for tunnel lining structure mechanics calculation, use a variety of methods such as specification, engineering analogy, theoretical derivation with structural design, such as for tunnel cross-section shape and size design of the engineering analogy method from Qingdao city subway tunnel engineering experience, for coefficient of mater
