	%X The launching nose plays an important role in the
incremental launching construction. The parameters of the launching
nose essentially affect the internal forces of the girder during the
construction. The appropriate parameters can decrease the internal
forces in the girder and save the material and reduce the cost. The
simplified structural model, which is made with displacement method
according to the characteristic of incremental launching construction
and the variation rule of the internal forces, calculates and analyzes the
effect of the length, the rigidity and weight of launch nose on the
internal forces of girder during the incremental launching
construction. The method, which can calculate the launching nose
parameters for the optimum incremental launching construction, is
achieved. This method is simple, reliable and easy for practical use.
