Rail linear control method for multi-line high speed railway bridge

The invention belongs to the technical field of bridge engineering and particularly relates to a rail linear control method for a multi-line high speed railway bridge. The method comprises the following steps of A, railway line construction sequence determining, B, foundation constructing, C, accessory construction and D, rail paving. According to the rail linear control method for the multi-line high speed railway bridge, specifically, all railway lines can be successively opened to traffic for the multi-line high speed railway bridge according to the traffic opening time sequence requirements of the step A, the railway line which is firstly opened to the traffic is put into use in advance, thus the condition that railways are put into use as soon as possible is ensured, and therefore economical performance in the railway construction process is ensured; and the linear influence of follow-up rail paving work on paved rails is also greatly reduced, and therefore the condition that all line rails have good lin
