摘　　要：地质条件是隧道施工需要考虑的重要因素,地质的软弱程度会直接影响到最终施工质量,尤其是在大跨度隧道工程中,浅埋黏土层地质环境下,若技术实施不当,可能会引发塌方等安全问题。为保证大跨度隧道施工质量,同时有效防范塌方风险,结合典型黏土层浅埋大断面隧道工程实例,围绕工程概况、技术难点深入分析施工工艺,根据地质雷达超前预报分析塌方风险,确立风险防范方案,以保证工程安全作业。Geological conditions are an important factor to consider in tunnel construction,and the degree of geological weakness directly affects the final construction quality,especially in large-span tunnel engineering.In shallow clay geological environments,if the technology is not implemented properly,it may lead to safety issues such as landslides.In order to ensure the construction quality of large-span tunnels and effectively prevent collapse risks,combined with typical examples of shallow buried large-section tunnels in clay layers,the construction process is analyzed in depth around the project overview and technical difficulties.Based on geological radar advanced prediction and analysis of collapse risks,a risk prevention plan is established to ensure safe operation of the project.
