摘要：
The AutoCAD software drawing method is commonly used for the design of segment dimensions of a shield tunnel. However, some approximations and a cumbersome design process make the results hard to be verify. In this paper, an analytic formula associated with segment dimensions is derived based on knowledge of analytic geometry and segment structure characteristics. The analyses show that not only can an exact solution of segment dimensions be achieved by using this method, but also that design efficiency can be improved and drawing results can be verified conveniently.
