Summary:The invention discloses a temporary pier elevation determination method for a girder few-fulcrum erection method, which comprises the following steps of: sequentially numbering each temporary pier as Nj along the girder erection direction, j = {1, 2, 3...}; according to the linear relation between the deflection of the maximum cantilever state before the main beam is erected to the temporary pier Nj and the height of a pad needing to be arranged on the temporary pier Ni when the main beam is just erected on the temporary pier Nj, the total height delta hi of the pad of the temporary pier Ni when the main beam is just erected on the temporary pier Nj is calculated, and i = {1, 2, 3...} and ilt; j; and the delta hi and the beam bottom elevation f0 manufactured at the temporary piers Ni according to the line shape of the main beam are overlapped, and the elevation Hi of each temporary pier Ni when the temporary piers Nj are arranged on the main beam is obtained. According to the method, a reserved height empiric
