云南大保路四角田隧道围岩变形监控量测及控制措施

Deformation Monitoring and Control Measures of Sijiaotian Tunnel

云南大保路四角田隧道是一个在复杂地质条件下修建的隧道,对四角田隧道的围岩变形监控量测,分析了产生较大变形的原因,同时提出了控制的措施。配合指导现场施工,确保了隧道施工的安全和结构的稳定性。

Located in Yunnan Province,Sijiaotian tunnel built in complex area. The deformation of wallrock of the tunnel was monitored, its reason was analyzed, meanwhile,the controlling measures were put forward. The conclusion is instructive for future engineering construction.
