The invention discloses a positioning method of a tunnel disease in a three-dimensional live-action model. The positioning method comprises the following steps: obtaining tunnel center line vector data through a tunnel plane design drawing; according to the tunnel center line vector data, calculating a center point coordinate # imgabs0 # of each lining ring forming the tunnel; constructing a geometric figure between the disease ensemble point and a central point of the lining ring where the disease ensemble point is located, calculating a disease height value H and a disease ensemble point coordinate # imgabs2 # through a disease angle value theta, the size of the lining ring and a central point coordinate # imgabs1 #, and forming a disease ensemble point three-dimensional coordinate # imgabs4 # by the disease height value H and the disease ensemble point coordinate # imgabs3 #; and according to the three-dimensional coordinates # imgabs5 # of the disease ensemble points, positioning and displaying the diseas
