设计题目: 隧道不良地质段的支护措施的研究
中 文 摘 要
本文介绍了隧道不良地质段的各种不良地质的支护情况,分析了各种不良地质对隧道施工的危害,通过对各种不良地质情况进行分类研究,通过研究把隧道不良地质状况分为以下几类:
一、V 级及IV 级较破碎围岩。
二、较干燥、凝结力差的岩层、断层带、V 级软弱围岩无水带。
三、浅埋段、含水断层破碎带、V 级及V级围岩以下围岩段。
四、富水地层且涌水量较大、掌子面稳定性较差、松散土层。
五、掌子面开挖期间不能自稳。
通过对以上五类进行分析,提出对以上五类的设计和施工解决方案。最用表格把各种不良地质情况所对应的支护方法进行总结。

ABSTRACT
In this paper, the geological section of the tunnel undesirable adverse geological support to analyze a variety of adverse geological hazards of the tunnel construction through a variety of adverse geological conditions of the classification study, by studying the adverse geological conditions of the tunnel is divided into the following several categories: 1.V level and the more broken rock class IV. 2. more dry, condensation force poor rock, fault zone, V-grade water with soft rock. 3. shallow, water-bearing fracture zone fault, V-class and V class rock surrounding the following paragraph, strict control of the surface deformation of the lot. 4. water-rich strata of Water and a larger working face is less stable, loose soil.
5. during the excavation can not be working face homeostasis.
Carried out through the above-mentioned five categories of analysis, the above-mentioned five categories of design and construction solutions. The most used form a variety of adverse geological conditions to the corresponding method of summing up the support.
Keywords:
