Regional sustainable development impact through sustainable bridge optimization

[EN] This paper describes a regional optimal model curve equation to measure and calculate sustainable development assessment impact data related to infrastructure construction in any world region. The article uses a literature review and a case study as research methods¿the literature review analyses the importance, practical significance, and current research status of this field. The case study application establishes a scientific algorithm program and a three-dimensional structural topology optimization interactive environment research model. The optimality of the influence equation curve and the sustainable development influence curve of China¿s large-scale cable-stayed bridges and regional infrastructure is analysed. This research will fill a gap by solving construction industries¿ tedious and complicated work and sustainable development assessment. Simultaneously, it will provide a theoretical basis and scientific calculation methods for governments and countries to formulate relevant laws and regulations and study regional climate effects.
