摘要

本文介绍了一个数字孪生（DT）平台，该平台集成了贝叶斯优化（BO）、分类提升（CatBoost）和非优势排序遗传算法（NSGA）-III 的在线优化算法。该平台可在不同地质条件下对盾构参数进行多目标动态优化。以武汉地铁为例，验证了该方法的有效性。结果表明(1) DT 模型准确估计了盾构机性能，在三种地质条件下测试集的 R2 不小于 0.957；(2) 在线优化显著提高了盾构机性能，在所有条件下综合优化改进超过 25%；(3) 所构建算法的准确性与 Shapley 加解法的比较证实了所建议算法的准确性、可解释性和通用性。

Intelligent dynamic control of shield parameters using a hybrid algorithm and digital twin platform

This paper presents a digital twin (DT) platform integrated with an online optimization algorithm that combines Bayesian Optimization (BO), Categorical Boosting (CatBoost), and the Nondominated Sorting Genetic Algorithm (NSGA)-III. The platform enables multi-objective dynamic optimization of shield parameters under varying geological conditions. Using the Wuhan Metro as a case study, the effectiveness of the method is validated. The results demonstrate that: (1) the DT model accurately estimates shield machine performance, with an R² of no less than 0.957 on the test set across three geological conditions; (2) the online optimization significantly enhances shield machine performance, with a comprehensive optimization improvement of over 25 % across all conditions; (3) comparison of the constructed algorithm's accuracy, along with Shapley additive explanations, confirms the accuracy, interpretability, and universality of the proposed algorithm.
