Method for treating tunnel stress cracks and deformation by adopting basalt fiber concrete

The invention discloses a method for treating tunnel stress cracks and deformation by adopting basalt fiber concrete. The method comprises the following steps: step 1, carrying out full-section treatment on a concrete surface with tunnel surrounding rock stress cracks, deformation, insufficient lining strength or insufficient thickness; step 2, fixing grids on the surface of the treated concrete; when the grids are fixed, the adjacent grids are in lap joint; 3, an interface agent is sprayed on the grids; 4, basalt fiber concrete is sprayed on the interface agent, and the basalt fiber concrete is flattened; the basalt fiber concrete adopted by the invention has ultrahigh mechanical property, anti-seepage property and durability, and can effectively improve the bearing capacity of the original tunnel structure. 本发明公开了采用玄武岩纤维混凝土治理隧道应力裂缝和变形的方法，包括：步骤1：在隧道围岩应力裂缝、变形、衬砌强度不足或厚度不足的混凝土表面进行全断面处理；步骤2：在处理后的混凝土表面固定网格；在固定网格时相邻的网格之间进行搭接；步骤3：在网格上喷涂界面剂；步骤4：在界面剂上喷射玄武岩纤维混凝土并将玄武岩纤维混凝土抹平；本发明采用的玄武岩纤维混凝土具有超高力学性能、防渗性能与耐久性能，可以有效提高原有隧道结
