摘　　要：岩溶区盾构施工因复杂的地质条件易引发突水、突泥和地层沉降等事故。本文以徐州地铁工程为例,提出基于光纤传感等技术的管片变形、地表沉降、地下水与孔隙水压实时监测方案,进一步搭建了智能预警平台。研究结果表明,该系统能够及时识别和响应施工风险,为盾构施工提供了科学的决策支持,具有良好的应用前景。Due to the complex geological conditions, shield construction in karst area is prone to accidents such as water inrush, mud inrush and stratum settlement. Taking the Xuzhou Metro Project as an example, this paper constructs a monitoring scheme for segment deformation, surface settlement, groundwater and pore water compaction based on optical fiber sensing and other technologies, and further builds an intelligent early warning platform. The results show that the system can identify and respond to construction risks in a timely manner, which provides scientific decision support for shield construction and has a good application prospect.
