Abstract：Abstract :Research purposes : Lanzhou - Xinjiang high - speed railway passes through the 50 - km wind area，in order to reduce the wind ；fects on the safety of high speed railway in operation phases，the wind - resistant gallery was first proposed and designed in the core area of tlie 50 - km wind region. The structural style of wind - resistant gallery was determined and the construction technology，connection type，ventilation lighting and pressure relief holes were studied based on the characteristics of tlie strong wind and wind - resistant gallery. Research conclusions:( 1) The wind - resistant gallery consists of the pile foundation，longitudinal beam and concrete vault. (2)The construction method with the factory prefabrication and on - site consolidation is applied in the wind - resistant gallery. (3 ) The rigid connection technology with shape steel and post - poured concrete is applied in the precast segment. (4) In order to implement the function of natural lighting， natural ventilation and relieve the aerodynamic effect，ventilation lighting and pressure relief holes are designed in the leeward side of the wind - resistant gallery. The research results can be used for the protection engineering in highway and railway that located in the environmental sensitive area，and also can be used for the reference for the similar engineering construction.
