摘要
以上海地区某双孔盾构隧道中试验段的施工为仿真对象,在现有多种计算方法的基础上,进一步突出盾构机施工工序和细节模拟,建立了大规模的全三维动态仿真模型,最后在高性能计算平台上结合并行求解算法完成了一系列计算.仿真结果显示了施工引起的具体地表三维隆沉情况,通过实测数据验证计算模型的合理性;同时也研究了不同并行求解方案对大规模盾构隧道开挖模拟的影响.
Aiming at the construction of the testing section for a tunnel in Shanghai, this paper emphasized and expatiated on the simulation of the sequence of shield tunneling procedure based on the current simulation methods. The large-scale three-dimensional dynamic model was established and then calculated on a high-performance computing platform with parallel algorithm. The results show the detailed ground deformation, and validate the rationality of this numerical model with monitoring data. The influence of various solving schemes on calculation efficiency was also investigated.
