This paper takes a new shield tunnel as the research object, which intends to cross a section of a high speed railway. Based on design specifications and the existing monitoring data to analyze the change rule of track irregularities, this article proposes the control of wavelength and relevant amplitude in the above case, following the design specifications and long-wave irregularity management demands of high-speed highway. And the controlling values of wavelength and amplitude required are presented with the outcome of the range of the settlement trough, drawn out of the under-crossing process. And it also uses large-scale non-linear finite element analysis software to simulate the high speed railway track deformation in actual constructions, to test whether the deformation meet the requirements of the control standards and deformation law. The results can provide reference for the construction measure when shield tunnel under crosses the high speed railway in the future.
