The construction of the Proton Therapy Center of Wuhan Union Hospital puts forward special requirements on structural design.The project overview and design conditions were introduced in detail.The main design points of foundation,basement and superstructure were described,including the selection of pile foundation,structural joint setting,structural scheme,large span and other special parts treatment methods.For the structural design of the proton region,the key problems such as settlement control,vibration control,radiation protection and hoisting hole design were discussed.In the process of structural design,the above problems were well solved by setting of structural joints,optimizing the design of pile foundation,adopting large thickness wall board and heavy density concrete,and designing special prefabricated beams.Meanwhile,some good results were achieved by using these methods,such as environmental investigation,numerical simulation and field measurement.The structural design can meet the architectural functional and special process requirements of the proton hospital.
