摘要:
依托大石包隧道进口段工程项目，以管棚支护技术为研究对象，选择外插角、拱顶加固范围、环向间距和拱顶加固距离为影响隧道稳定性的主要评价指标，借助ABAQUS 数值软件进行正交试验，采用CRITIC 法求解客观权重，结合G1 法所求的主观权重在引入博弈论后进行权重组合优化，并基于改进TOPSIS 法加权后探讨了在多因素同时改变的管棚支护工况下各评价指标的变化情况。 最后对各工况结果进行分析，确定最优方案，将最优方案与实测数据进行对比，验证了该方法的可行性，可为类似隧道工程提供参考。
Abstract:
Based on the tunnel project of the inlet section of Dashibao, the tube shed support technology was used as the research object, and the outer insertion angle, vault reinforcement range, circumferential spacing and vault reinforcement distance were selected as the main factors affecting the stability of the tunnel. Orthogonal tests were conducted with the help of ABAQUS numerical software, and the objective weights were solved by the CRITIC method. Combined with the subjective weights obtained by the G1 method, weight combination optimization was carried out after the introduction of game theory. Changes of each evaluation index under the working condition of the tube shed support with multiple factors changed simultaneously are discussed based on the improved TOPSIS method. Finally, results of different working conditions were analyzed, the optimal scheme was determined, and the optimal scheme was compared with the measured data to verify the feasibility of the method, which can provide reference for similar projects in the future.
