摘要
在西安地铁永(永宁门)-南(南稍门)区间隧道施工过程中,由于多天连续暴雨导致管线断裂,造成隧道涌水、道路坍塌。事故发生后及时启动了应急预案,并通过采用加强拱脚、扇形支撑、注浆加固及组合工法为技术要点的综合处理方案,有效地控制了隧道变形,保证了工程建设的安全快速。
Due to a continuous rainstorm, pipeline breakage, water inflow, and a road collapse occurred during the construction of the running tunnel from Yongningmen station to Nanshaomen Station of the Xi'an metro. The emergency response plan was initiated in time and the comprehensive treatment measures, such as reinforcement of the tunnel arch springing, umbrella support, and grouting, were adopted, effectively controlling tunnel deformation and ensuring safe and rapid tunnel construction.
