This paper considered the adverse effects of ventilation in clip wall air channel caused by civil engineering such as the uneven rock wall and anchor cable, established experimental models for flow characteristics and related solutions of a certain clip wall air channel at the Baihetan hydropower station based on the similarity theory, presented the composition of the model system and the testing method, demonstrated the feasibility of solutions by model experiments, and analyzed the effect of different installation positions of the fan in clip wall air channel. New ideas were provided for the design of clip wall air channel influenced by rock wall and anchor cable. What ’s more, it provided reference for the underground hydropower station construction in the future. Keywords:clip wall air channel, underground hydropower station plants, similar model experiment, rock wall and anchor cable ★ Chongqing University, Chongqing, China 1 作者简介：郭敏 （1995.2— ），女，在读硕士研究生，E-mail: 1311594884@ 通讯作者：肖益民 （1974.2— ），男，教授，博导，E-mail:xiaoyimin1974@126.com 。中国电建集团华东 勘
