随着国家“十三五”规划和“一带一路”战略构想的实施，我国已是隧洞（道）修建规模和难度最大的国家，隧道富水断层破碎带渐进失稳突水突泥灾变演化过程模拟分析方法可用于指导突水突泥灾害预测与防治，具有重要的理论研究与工程应用价值。项目研究依托大瑞铁路高黎贡山隧道、新疆**工程和川藏铁路等国家重大项目，紧密结合申请人博士期间的科研工作，针对数值仿真的三个重要方面“数值建模、计算模型和程序算法”，提出断层破碎带三维地质建模与网格划分方法，揭示颗粒流失过程中充填介质孔隙率、渗透率、刚度和强度的变化规律，建立充填介质流失断层破碎带渐进失稳突水突泥流固耦合模型，基于并行自适应非线性变形分析软件平台（PANDAS），解决断层破碎带计算非线性变形引起的收敛性难题，建立断层破碎带渐进失稳突水突泥灾变演化过程模拟分析方法。研究成果可应用于交通、水电、采矿及海底隧道建设等领域，具有广泛的应用前景。

With the implementation of the national 13th five-year plan and the strategic concept of "One Belt And One Road", China has the most tunnels. Whole process simulation method for water and mud inrush due to progressive instability of fractured rock mass in water-rich fault can be used to guide the prediction and prevention of water and mud inrush, which has important value in theoretical research and engineering application. The research of the project relies on the gaoligongshan tunnel of dalui railway, xinjiang ** project and sichuan-tibet railway and other major national projects and closely combined with the applicant's research work during the doctoral period. For the three important aspects of numerical simulation "numerical modeling, computational models and procedural algorithms", a method of 3d geological modeling and meshing of fault fracture zone is presented, the variation rules of porosity, permeability, stiffness and strength of filling media during particle loss were revealed, a coupling model of water and mud inrush in the fracture zone was established, the convergence problem caused by calculating nonlinear deformation of fault fracture zone is solved, and based on PANDAS the whole process simulation method for water and mud inrush due to progressive instability of fractured rock mass in water-rich fault is established. The research results can be applied in the fields of transportation, hydroelectricity, mining and the construction of undersea tunnel.
