摘要
本文通过西南某山区铁路斜坡软土地段的软岩隧道施工所揭示的工程地质问题,浅述了对炭质页岩、泥灰岩岩性的初步认识和采取的施工对策,重点介绍了软岩隧道浅埋洞口段施工技术,及富水软岩破碎段施工支护开裂变形,衬砌混凝土开裂的原因分析及处理技术。
The article discusses the elementary understanding of carbonaceous shale and argillaceous shale lithology and also dissertates the construction measures that were adopted in the engineering through the project geological problems in the construction of sotf rock tunnel which is located in the railway shope soft ground of a mountainous area southwest china.It also emphasize on introducing the soft rock tunnel entrance section construction techniques and discussing the reason analysis and treatment technology of the construction shoring distortion in hydrous soft rock crashed section and concrete masonry for supporting.
