本地铁项目区间岩溶发育,盾构施工存在较大的安全隐患,易使盾构机姿态不稳,造成安全事故,后期处理非常困难。为了确保盾构机安全掘进,需要对沿线溶洞进行处理。
Karst development in the local railway project area has great potential safety hazards in the shield construction. It is easy to make the posture of the shield machine unstable and cause a safety accident. Post-processing is very difficult. In order to ensure the safe excavation of the shield machine, the karst cave needs to be dealt with.
