Abstract
In response to the complex geological conditions encountered during the tunnel construction for a large-scale water diversion project,and combined with practical engineering experience,systematic optimization was made to the tunnel support system,lining structure and grouting construction technique.By adopting a composite support system,the deformation of the surrounding rock was effectively controlled;the improved structural design and construction technique of the lining solved the problem of lining cracks;and the optimized application of intelli-gent grouting system and segmented grouting technology significantly improved the impermeability effect.Engineer-ing practice has shown that the optimized construction technical scheme is safe and reliable,with a significant im-provement in construction quality,a 15%reduction in construction time,a 12.3%saving in investment,and achiev-ing good engineering benefits.关键词
