探析松散地层对隧道预支护工程影响

On analysis of influence of loose strata on tunnel pre-supporting projects

对松散地层的概念、特征、判别和分类进行了阐述,将松散地层变形破坏机理及力学性质作了分析,并对松散地层的预支护方法进行了论述,进而研究了松散地层对隧道预支护的影响,具有重要的指导意义。

The paper illustrates the concepts, the features, the judgment and the classification of the loose strata, analyzes the deformation dam- age mechanism and the dynamic features of the loose strata, indicates the pre-supporting methods of the loose strata, and researches the influence of the loose strata on the tunnel pre-supporting, so it has important directive significance.
