Abstract：Aiming at the construction of arch roof concrete in finger gate chamber in underground mine,formwork supporting frame was set up and the mechanical properties of supporting system were analyzed.The advantages and disadvantages of fastening-type steel pipe scaffold,bowl buckle scaffold and socket and disc buckle scaffold were compared,the scheme design adopted socket type disk-buckle steel pipe full support scaffold,used the finite element method to calculate the arch form-work support frame,and checked the deformation,combined stress and stability of the support sys-tem to meet the standard requirements.By using the finite element software MIDAS Civil,the finite element model of the formwork support of the fingerlike access gate operation chamber was estab-lished,which solved the problems of difficult calculation of arch roof and inaccurate calculation of the plate approximation,and provided a reference for the design and analysis of arch form work support system.
