Special Issue Information

Dear Colleagues,

As civil and structural engineering increasingly confronts complex challenges in sustainability, resilience and digitalization, the role of intelligent optimization algorithms and advanced computational modeling has become paramount. This Special Issue aims to capture the latest, cutting-edge research at this interdisciplinary frontier.

We welcome original research articles and reviews that explore innovative methodologies. This Special Issue invites contributions across several key pillars, including (but not limited to): intelligent optimization (e.g., metaheuristics, genetic algorithms), advanced computational modeling (e.g., finite element method, discrete element method), machine learning and data-driven approaches (e.g., deep learning, neural networks) and intelligent construction technologies (e.g., digital twins, automation).

A key focus of this issue is algorithmic development and methodological innovation within all these domains. We strongly encourage submissions that propose novel algorithms, advanced theoretical frameworks, new model-coupling techniques (e.g., physics-informed machine learning), computational efficiency improvements or new validation methods. We are equally interested in theoretical advancements in optimization and machine learning as we are in new constitutive models for FEM/DEM or novel data-fusion algorithms for intelligent construction.

Research areas may include (but are not limited to) structural optimization, construction management, seismic resilience, infrastructure health monitoring and life-cycle performance. This Special Issue seeks to bridge the gap between theoretical algorithmic development and practical engineering applications, fostering solutions for a truly intelligent and resilient built environment.

Accurate prediction and optimized control of shield tunneling attitude are critical for ensuring tunneling quality and construction safety. In karst and other highly heterogeneous strata, complex geological conditions and construction parameters exhibit significant nonlinear coupling, greatly increasing the difficulty of attitude regulation. To address this challenge, this study proposes a machine learning-based approach for the automatic control of shield tunneling attitude. First, a Tree-structured Parzen Estimator-optimized Light Gradient Boosting Machine predictive model is employed to construct a nonlinear mapping model between construction parameters and shield tunneling attitude. Subsequently, the SHapley Additive exPlanations (SHAP) interpretability model is introduced to identify the core tunneling factors influencing attitude stability. On this basis, the developed predictive model is integrated into the multi-objective evolutionary algorithm based on decomposition (MOEA/D) framework as a fitness function to achieve multi-objective optimization of key construction parameters. Using field data from shield tunneling construction in the karst strata of Shenzhen Metro Line 16, the proposed model achieved prediction accuracies of R2 = 0.959 for pitch and R2 = 0.936 for roll, outperforming XGBoost, Random Forest, Long Short-Term Memory, and Transformer baselines. SHAP analysis identified the partitioned propulsion thrust, partitioned chamber pressure, cutterhead rotational speed, and advance rate as key parameters influencing attitude. Further, MOEA/D optimization generated a Pareto set of construction parameters, from which the optimal solution was selected using the ideal point method, resulting in reductions of 26.45% and 39.47% in pitch and roll deviations, respectively. These findings demonstrate the feasibility and effectiveness of the proposed method in achieving high-precision prediction and intelligent optimization control of shield tunneling attitude under complex geological conditions, providing a reliable technical pathway for metro and tunnel construction projects.
