Description
technical field [0001] The invention belongs to the technical field of subway shield tunnel construction engineering, and in particular relates to a device and method for determining the circle center of a subway tunnel section. Background technique [0002] At present, with the expansion of China's urban construction scale and rapid economic development, the urbanization process is accelerating, and the traffic demand is expanding. The advantages of the subway are becoming more and more obvious and popular in more and more cities. Better technical approaches make higher demands. The traditional method of determining the coordinates of the center of the circle is mainly used in the construction of the subway shield method. The inner edge of the rigid ring of the portal is abstracted into a three-dimensional space circle, and the three-dimensional space circle is converted into a plane intersecting with a spherical surface, and the plane and the spherical surface are respect...
