摘　　要：为准确了解海底隧道掌子面前方地质状况,综合多种地质预报手段,建立海底隧道超前地质预报综合体系,以小断面服务隧道先行施工兼作地质导洞,以掌子面水平超前钻孔为主,以TSP203、红外探水、地质雷达等物探为辅,结合掌子面地质素描,进行综合预报。该体系应用于厦门翔安海底隧道左线隧道F1风化槽,准确探明掌子面周围及前方不良地质体的规模、形态、岩性和水文地质条件,为设计和施工提供可靠的地质保障,预报成果得到开挖验证。In order to accurately forecast the geological condition ahead of the tunnel face,a comprehensive advanced geological forecast system is establishedfor subsea tunnel.The system runs in such a way that the small-section service tunnel is constructed in advance as pilot tunnel,geological information is obtained from horizontal advancing holes ahead of tunnel face and geophysical prospecting includes TSP203,infrared water detecting,ground penetrating radar,as well as geological sketch of the tunnel face.The system is introduced to F1 Fault of Xiamen Xiang'an Subsea Tunnel,the scale,morphology and lithology of the unfavorable geological body and the hydrogeology condition ahead of tunnel face are accurately predicted and verified by excavation,which presents accurate geological condition for designing and tunneling.
