摘要	A two-stage particle collider, i.e., CEPC-SppC, is proposed by the Institute of High Energy Physics (Beijing, China). The circular electron-positron collider (CEPC) will be upgraded to a super proton-proton collider (SppC) after the first-stage experiment. According to the requirement of SppC, the field strength of the main dipoles is 20 T, and 10(-4) level field uniformity should be reached within two thirds of the aperture. The outer diameter is restricted to be 900 mm. The magnetic design study of a 20-T two-in-one common-coil dipole magnet has been done and previously presented. This paper mainly focuses on the corresponding mechanical design study by establishing a two-dimensional finite-element model with a shell-based structure. The water-pressurized bladder is adopted to apply the preload on coils with the pressure of 80 MPa. The peak coil stress is minimized to reduce the critical current degradation of superconductors. An appropriate aluminum shell thickness is selected to overcome the significant Lorentz force under the restriction of the main dipole's outer diameter.
