| 摘 要： | 对位于新疆霍城县约50 km处西气东输二线工程果子沟1#隧道南口的地质安全进行研究.1#隧道所处区域为北天山褶皱带中山峡谷区,工程地质条件复杂,岩层主要为石灰岩.工程地质安全隐患为进硐口的危岩崩塌、不稳定斜坡、弃渣边坡和围岩稳定性.对隧道围岩计算得出岩体强度应力比均大于6,该隧道围岩能够承受围岩应力的作用,不会产生过大的整体塑性变形、剪切及弯折等变形破坏,但围岩中存在分离块松动坍塌的可能性,从预防、治理和监测三个方面提出了对策建议. |
| 关 键 词： | 围岩稳定性 围岩分类法 工程地质 工程地质安全 |

| Abstract: | The south entrance of Guozigou No.1 Tunnel,50km away from Huocheng County in Xinjiang,in the Pipeline Project II of West To East Gas Transportation was located in the middle mountain and steep gorge area of north Tianshan folding belt.Engineering geological conditions in the Guozigou tunnel No.1 were complicated.Country rocks are mainly limestone.There exist some crag rockfall,unstable slope,tunnel construction dregs' slop and country rock stability in the entrance of Guozigou No.1 tunnel.As strength stress... |
| Keywords: | country rock stability country rock classification engineering geology engineering geology security |
