Abstract

The construction and management of large-scale projects have the characteristics of complexity, dynamic and offline, and how to evaluate it is a research problem accurately. This study addresses this question through multidisciplinary cross-applied research. The research analyses and optimizes the environmental impact of the construction stage of superlarge bridges by establishing a theoretical model system of environmental impact resilience. The analysis shows that industrialized construction can save 56.31% of materials compared with traditional construction but increase the consumption of machinery and personnel by 11.18%. Ultimately, environmental pollution can be significantly reduced. This study breaks through the difficulty of accurately evaluating discrete dynamic factors. It has realized the application of multidisciplinary research to solve management optimization and design problems in the elastic and dynamic changes of super-large bridges during construction. This research provides rich theoretical models and advanced analytics experience data for environmental resilience impacts and project resilience management models, laying a solid scientific foundation for dynamic control and sustainable development assessment of statically indeterminate structures in the future.

基于弹性理论的桥梁施工碳影响评价

大型项目的建设和管理具有复杂性、动态性和离线性的特点，如何对其进行准确评价是一个研究问题。本研究通过多学科交叉应用研究来解决这个问题。本研究通过建立环境影响恢复力理论模型体系，对特大桥施工阶段的环境影响进行分析和优化。分析表明，与传统建筑相比，工业化建筑可以节省56.31%的材料，但增加了11.18%的机械和人员消耗，最终可以显著减少环境污染。这项研究突破了精确评估离散动态因素的困难。实现了多学科研究的应用，解决了特大型桥梁施工过程中弹性和动力变化的管理优化和设计问题。本研究为环境恢复力影响和项目恢复力管理模型提供了丰富的理论模型和先进的分析经验数据，为未来超静定结构的动态控制和可持续发展评估奠定了坚实的科学基础。
