摘要/Abstract

摘要： 针对超大直径盾构隧道所面临的施工期管片上浮问题，依托江阴靖江长江隧道工程，建立了考虑浆液时变特征的三维有限元计算模型。使用有限元软件ABAQUS（2016）对模型进行求解，并将计算结果与实际工况的监测数据进行对比，验证了模型的正确性。结合模拟结果，分析了地层压缩性、注浆压力值大小、注浆压力持续时间对管片上浮的影响。引入单因素敏感性分析法，计算得到了各因素对管片上浮的敏感度。结果表明：地层压缩性的增强、注浆压力的增加、注浆压力持续时间的增加都将使盾构隧道管片上浮的现象加剧。管片上浮对各影响因素的敏感度从大到小依次为地层的压缩性、注浆压力的持续时间、注浆压力的大小。最后从实际工程的角度给出了针对性的管片上浮控制措施。

Abstract: To solve the problem of segment uplift during the very-large diameter shielded tunnel excavation, a three-dimensional finite element model considering the time-varying characteristics of grout is established based on the Jiangyin-Jingjiang Yangtze River Tunnel project. The commercial finite element software ABAQUS (2016) was used, and the simulation results were compared with the monitoring data of the actual working conditions to calibrate and validate the model. Combining the simulation results, the effects of geological compressibility, grouting pressure magnitude, and grouting pressure duration on segment uplift were analyzed. The sensitivity analysis method was introduced to evaluate the sensitivity of each factor on the segment uplift. The results show that the enhancement of geological compressibility, the increase of grouting pressure, and the increase of grouting pressure duration will aggravate the phenomenon of segment uplift in shielded tunnel excavation. The sensitivity of each factor to segment uplift is in the order of geological compressibility, duration of grouting pressure, and grouting pressure magnitude. Engineering-oriented control measures are given from the perspective of practicality.
