摘要
工程所处环境及地层赋存条件是十分复杂的,存在着随机性、模糊性、未知性等不定因素,因此对隧道施工过程中的围岩稳定性进行评估、围岩稳定性预警标准隧道变形预测一直是岩土工程中的研究难点,尝试提出了一种基于超前地质预报所获得的相关地质信息所建立的围岩稳定性模糊综合评估方法,能够在预测围岩稳定性方面取得较好的效果。
The engineering environment and existing stratum conditions are very complicated with the uncertainties of randomness, fuzziness and unknown. Therefore, the evaluation of surrounding rock stability, the early warning standard of surrounding rock stability and the prediction of tunnel deformation are always the study difficulties in the construction process of tunnel. The article proposes a fuzzy synthetic evaluation method of surrounding rock stability established by the relative geological information based on the advanced geological prediction, which can achieve the better effect to predict the stability of surrounding rock.
