介绍了高阳寨隧道出口、大瑶山一号隧道出口、九峰河导流洞进口、赛里木湖隧道出口、中咀二号隧道出口不同的山体偏压，采取的不同施工技术措施，确保了施工安全。隧道洞口山体偏压在进洞前事先宜处理，山体偏压不宜采用卸载方式处理，山体偏压段洞内施工时宜先施工深埋侧，下台阶开挖宜从洞内向洞外施工；若已进洞而山体位移，必须采用洞内、洞外处理，先后顺序根据现场实际情况决定。

The unsymmetrical load conditions and countermeasures for the construction of the exit portal section of Gaoyangzhai tunnel, the exit portal section of No. 1 Dayaoshan tunnel, the entrance portal section of Jiufenghe diversion tunnel, the exit portal section of Sayram lake tunnel and the exit portal section of No.2 Zhongzui tunnel are presented. It is concluded that the unsymmetrical loads of the tunnel portal sections should be treated prior to the commencement of the tunnel excavation, unloading method should not be used for the unsymmetrical loads, insidetunnel construction should be first made on the deepburied side in tunnel sections under unsymmetrical loads, the bench excavation should be made in the direction from the inside tunnel toward the portal, and insidetunnel treatment measures and outsidetunnel treatment measures, which should be taken in an order that depends on the actual conditions in the site, must be taken in case that displacement occurs to the mountain after the tunnel excavation has been started.
