Summary:The invention provides a method and a system for evaluating the variability of tunnel surrounding rock based on the working parameters of a TBM stabilizer, wherein, the method comprises the followingsteps of: collecting the pressure and travel data of a stabilizer cylinder of the TBM system; stabilizer pressure for different cycles is obtained from the stabilizer cylinder pressure and stroke dataSlope of stroke relation curve; based on the slope of pressure-stroke relationship curve obtains the slope distribution of the stabilizer pressure-stroke relation curve in different cycles so as to obtain the evaluation results of the surrounding rock variability of the tunnel. This method can solve the problem that the surrounding rock can not be observed directly because of shield shield shieldin TBM construction, and can obtain the variability of surrounding rock accurately and comprehensively. 本发明提出了种基于TBM稳定器工作参数的隧道围岩变异性评价方法及系统，其中，该方法包括：采集TBM系统的稳定器油缸压力和行程数据；根据稳定器油缸压力和行程数据获取不同循环时稳定器的压力-行程关系曲线的斜率；根据压力-行程关系曲线的斜率获取不同循
