摘要

断裂构造对于岩体的工程性质起着十分重要的作用。建设中的十漫 (十堰至漫川关) 高速公路，地处两郧断裂带穿越地区。结合该段最长的隧道——二道垭隧道左、右隧道不同围岩类别与特征，分析了两郧断裂带的影响。针对隧道不同围岩类别，探讨了不同的开挖和支护方法，并就其施工效率和成本进行了比较分析。研究成果表明

断裂构造对隧道施工和稳定性有重要影响。高速公路选线应加强勘察，尽量避开断裂带，从而达到施工安全、迅速、经济的目的。

Abstract

Fracture structures of rock mass play an important role for the engineering properties. Expressway in building is located in fracture region of liangyun. The longest tunnel

Erdaoya Tunnel

is taken as a typical example in analysis. The rock classification and characteristic of the right and left tunnels are presented. Also

the influence of fracture region of Liangyun on them is studied. According to different rock classifications

the tunneling and supporting methods are analyzed. The construction effect and cost of the right and left tunnels are compared. The results show that the fracture structures have much influence on the construction and stability of the tunnels. In practice the geological investigation should pay more attention in choosing the expressway line. The tunnel should be far away from the fracture areas so that the construction may be safe

fast and economic.
