As a common structure of suspension bridge,the tunnel anchor has the characteristics of difficult excavation construction and complex construction environment,so it is necessary to carefully investigate the construction environment and formulate the excavation construction plan according to the obtained results to ensure the safe and smooth completion of the excavation construction.Starting from the key points of anchor excavation construction of suspension bridge tunnel,this paper expounds the construction methods such as early environmental investigation,mechanical excavation operation,tunnel anchor drilling and blasting construction,initial support,tunnel slag removal,secondary lining and other construction methods of suspension bridge soft rock tunnel anchor excavation and focusing on actual engineering cases,and puts forward quality control measures to provide experience guidance for similar engineering construction.
