汶川震中区桃关~#2隧道施工地质分析及对策
|
摘要
桃关#2隧道为映汶高速公路控制性工程,地处汶川震中区,隧道地质条件复杂,隧道开挖过程中遭遇崩塌堆积体、断层、软弱破碎带、岩爆及地下水等多种地质问题,严重影响了隧道施工进度及施工安全。从宏观及微观地质构造方面探讨上述地质问题的成因,找出工程地质变化的规律性,通过恰当的施工期地质超前预报技术,及时发现了隧道存在的复杂工程地质问题,并提出科学合理的对策措施。
Taoguan Tunnel 2,located in the epicenter area of Wenchuan,is a control project on YingxiuWenchuan Highway. There have very complex geological conditions with collapse deposits,faults,weakfracture zone,rock burst,groundwater and other troubles,seriously affecting the progress and the safety of tunnel construction. From the aspects of micro- and macro-tectonics,this paper discussed the geneses of the aforesaid geological issues,and then found out the change law of the engineering geology. Through proper geological advanced prediction technique,complex engineering geological issues arising out of tunnel may be found in time,and the scientific and reasonable countermeasures were proposed.
