The construction in the weak surrounding rock area will face the problems of weak surrounding rock,shallow burial depth,and partial pressure in geology,which will have high requirements for construction technology.Combined with the construction case of a four-lane highway tunnel,this paper determines the tunnel construction plan and expounds the tunnel construction method,aiming to ensure the safety of tunnel construction and improve the quality and efficiency of tunnel construction.Study and establish a tunnel monitoring and measurement system to monitor the changes in geological structure during construction,do a good job in tunnel construction support technology,ensure the safety of tunnel construction,and reduce potential safety hazards.
