青岛胶州湾海底隧道TSP203~+超前预报应用探讨
|
摘要
青岛胶州湾海底隧道工程,地质条件复杂,构造发育,洞身共穿越18条断层,岩体较为破碎,为避免工程措施不当引发的塌方和海水倒灌灾害,施工期间开展超前地质预报工作尤为必要。本隧道海底全程应用TSP203+技术,并利用专门的TSPwin物探分析软件对TSP203+成果进行解译、分析,对前端地质做出超前预报,经施工验证比较,预报结果符合现场实际情况。地下工程合理利用TSP203+技术,可以针对围岩的完整、风化、破碎情况和断层破碎带分布等做出超前预报。它是地勘工作在施工阶段的重要补充和延续,也是设计变更的重要依据。可靠的预报结果,可以为快速、及时、有效地规避隧道施工风险提供可靠的保障。
Qingdao Jiaozhou bay subsea tunnel engineering presents complicated geological conditions and structures,the hole body of the tunnel passes through 18 faults with broken rock bodies. To avoid improper engineering measures from triggering landslides and see water back flooding during the construction,advance geological forecast is of great importance. The undersea tunneling with the application of TSP203+technology,and the use of the special TSPwin geophysical analysis software to interpret and analyze the results of TSP203+to front-end geological advanced prediction,it has been verified by construction comparison that the prediction results conform to the actual situations.Underground engineering is reasonable to use TSP203+technology to predict in advance the completion,weathering,crushing and breaking of the surrounding rocks. I serves as supplementary and extension of geological exploration in the construction phase and as the important basis for design modifications.Reliable prediction results can rapidly,timely and effectively circumvent the risk of tunneling.
