基于施工现场实际情况、地质勘探资料和相关的设计资料,通过采用大型有限元软件Ansys对邻近桥桩隧道的施工过程进行模拟,分析了浅埋暗挖法施工对地表及桥桩的影响,根据分析结果优化了隧道施工现场的监控量测方案。为今后相似工程的施工及监控量测提供了借鉴和参考;此外,通过将数值模拟结果和施工现场的监测数据进行对比,验证了数值模拟结果的可靠性。
Based on the actual conditions of the construction site, geological exploration data and relevant design data, the construction process of the adjacent bridge piles and tunnels is simulated by using the large-scale finite element software Ansys. The effects of the construction by shallow burying and undercutting on the surface and bridge piles are analyzed. The results of the optimization of the tunnel construction site monitoring measurement program. It provides a reference for the construction and monitoring measurements of similar projects in the future. In addition, by comparing the numerical simulation results with the monitoring data at the construction site, the reliability of the numerical simulation results is verified.
