摘要
Abstract
Taking Foling Tunnel Project as the background,the relationship between uniaxial compressive strength and rebound strength is established by linear regression analysis technique;at the same time,volumetric joint and geostress which are hard to be measured are determined by experiential formula and method;then surrounding rock grading is carried out in accordance with the existing specifications.The practice has proved that this method is of simple and rapid operation,and optimizes the design parameters and adjusts construction method through comparing to the grading in the phase of survey and design.It offers a new grading way for tunnel surrounding rock.关键词
