摘要
为解决地铁区间联络通道开挖过程中出现的涌水问题,文章以南宁地铁某区间联络通道涌水为例,阐述了该联络通道涌水过程、发生原因及处理措施。实际应用效果表明,通过采用漏水引流、沙袋反压回填、降水、地面及隧道内注浆、管片支护等综合型加固处理措施,确保了该隧道及联络通道开挖面的安全。
In order to solve the water inflow problem during construction of the metro cross passage,the process,causes of water inflow and countermeasures were described by taking the Nanning metro as an example.The results show that the safety of tunnel and work face of cross passage are ensured by adopting the treatment measures of water leakage drainage,sandbag backfilling,dewatering,grouting at ground and inside of tunnel and segment support installation.
