摘要
某山区高速公路隧道洞口段位于炭质板岩地段,隧道在进洞80m后在初期支护中陆续产生裂缝、大变形等病害,本文描述了该隧道的病害特征,分析了该隧道的病害成因,并对病害处治措施进行了详细介绍.
The tunnel section of a mountainous highway tunnel is located in the carbonaceous slate section. After 80m of the tunnel, the tunnel will cause cracks and large deformations in the initial support. This paper describes the disease characteristics of the tunnel, analyzes the causes of the disease in the tunnel, and introduces the treatment measures.
