建设可持续桥梁工程是21世纪世界性的使命与挑战。基于正在建设的虎门二桥,提出了可持续桥梁工程的三大目标:促进社会、经济的可持续发展;生态与环境保护;全寿命经济成本最优。论述了合理设计、精细施工与科学维护是实现可持续桥梁工程的重要手段,并重点从项目规划、方案设计、详细设计、工程施工与运营维护等4个阶段对虎门二桥基于可持续发展目标的线位选择、具体方案比选、细节设计、工程质量保证措施、维护养护规划等方面的具体实践进行了简要介绍,对未来可持续桥梁工程的发展提供了参考和借鉴。
The construction of sustainable bridge project is the worldwide mission and challenge in the 21st century. Based on Humen Bridge under construction, three major goals of sustainable bridge engineering are put forward: promoting social and economic sustainable development; protecting ecological and environmental conditions; This paper discusses that reasonable design, fine construction and scientific maintenance are important means to achieve sustainable bridge engineering. The emphasis is laid on four aspects of project planning, program design, detailed design, construction and operation and maintenance. Based on the sustainable development goals Line selection of specific options, detailed design, engineering quality assurance measures, maintenance and conservation planning and other aspects of the specific practice of a brief introduction to the future sustainable development of the bridge project provides a reference and reference.
