The invention discloses an immersed tube tunnel end steel shell mounting and measuring method, and relates to the technical field of immersed tube tunnels. The method comprises the following steps: S1, setting a plurality of measuring points; S2, arranging a measuring pile at each measuring point; S3, installing a total station on one measuring pile, and installing prisms on the other measuring piles; S4, measuring the prisms by using a total station; S5, repeating the steps S3 and S4, and measuring each measurement pile to form a measurement coordinate network; S6, setting a virtual coordinate system in the measurement coordinate network to obtain a coordinate value of each measuring pile; S7, according to the coordinate values of the measuring piles, obtaining actual coordinate values ofthe measuring piles through adjustment calculation software; S8, pasting a reflector on the surface of the end steel shell; S9, erecting a measuring instrument on the measuring piles to perform three-dimensional coordinate data acquisition on the reflection points on the end steel shell; and S10, comparing the acquired three-dimensional coordinate data with theoretical data to adjust the mountingposition of the whole end steel shell. The installation and measurement precision of the end steel shell is improved.
