The high consumption of concrete is the current situation and status of the construction of drilling and blasting tunnel.Among the many factors affecting the excessive consumption of concrete,overexcavation is one of the main factors.Using 3D laser scanner measuring equipment,statistical analysis method,comparative analysis method to analyze the influencing factors of tunnel overdigging,and calculate the resulting tunnel concrete overconsumption,so as to find out the impact degree of the gap between the actual tunnel overdigging and the current regulations on the concrete overconsumption,and provide reference for the tunnel construction overdigging control.
