隧道围岩稳定性判定的应变反演方法
Strain Inversion Method for Judging the Surrounding Rock’s Stability in Tunnel
【摘要】 利用岩体的变形特性,通过测试隧道围岩应变出隧道净空实际收敛量,从而判定施工过程中隧道围岩的稳定性,为选取合适的支护时机和方式提供依据。工程实践表明该方法方便可行,数据可靠,是一种高效实用的隧道围岩稳定性判定新方法。
【Abstract】 This paper utilized the deformation characteristics of rock and expatiates on the strain test method of surrounding rock by which to judge the surrounding rock’s stability,and to choose the suitable opportunity and style of the secondary lining.This method was simple and feasible;the data were reliable,and was set up to make the judging for surrounding rock’s stability more effective.
