Abstract Abstract：Research purposes： In a high-speed railway station yard design, because of the terrain and investment restrictions, turnout combination on throat area takes special form, there are only 117 m distance between No. 42 and No. 18 turnout, under the premise of not change existing station layout, according to the catenary pantograph model and dynamic envelope line and the positioning column at the pull-out value of contact wire, the positioning column support device geometry and data switch, the research on the precise layout of switch catenary in throat area is carried out, catenary wire and switch are arranged by studying the geometric relationship, so as to ensure the safety of high-speed pantograph smooth through the crossing area, to avoid the transformation of civil engineering. Research conclusions： （1）The station layout does not changed, the guiding catenary type and simple non-crossing type layout is adopted, the auxiliary guiding OCS which between main line and side line is taken advantage of, and several groups of contact suspension space position are reasonably arranged.（2）The layout not only has the advantages of simple structure, to facilitate the inspection and maintenance work less, but also to meet the hard points and catenary system flexibility index, so as to ensure the pantograph high-speed through mainline, from mainline swich to sideline, and from side line swich to mainline with safety and quality of power supply.（3）The research results are adapted to the high speed railway catenary layout on the complex throat area, can be flexibly combined with station design, which can proride reference for catenary layout when the high speed railway is introduced into the existing railway lines under the limited condition of civil construction.
