摘　　要：本文研究了基于低碳理念的公路永临结构转换技术,旨在解决传统公路建设中临时道路与永久路面独立设计导致的资源浪费和高碳排放问题。该技术通过一体化设计,将临时道路与永久路面有机结合,采用“刚-柔”或“刚-半刚-柔”复合结构体系,显著提升了路面耐久性并降低了能耗与碳排放。研究从永临结构协调变形原理出发,优化了半刚性材料性能参数,提出了“变形梯度调控层”概念,有效缓解了变形不协调问题。通过量化分析,该技术在材料生产阶段节能率达26.8%,减排率达25.6%;施工阶段节能率达40%,减排率达35.7%。工程实测数据与模拟结果一致,验证了其显著的低碳性能。该技术为公路建设行业的可持续发展提供了新的技术路径。This paper studies the transformation technology of highway permanent and temporary structure based on the concept of low carbon,aiming to solve the problems of resource waste and high carbon emissions caused by the independent design of temporary road and permanent pavement in traditional highway construction.Through the integrated design,the technology organically combines the temporary road with the permanent pavement,and adopts the“rigid flexible”or“rigid semi-rigid flexible”composite structure system,which significantly improves the pavement durability and reduces energy consumption and carbon emissions.Based on the principle of coordinated deformation of permanent and impending structures,the performance parameters of semi-rigid materials are optimized,and the concept of“deformation gradient control layer”is proposed,which effectively alleviates the problem of incompatible deformation.Through quantitative analysis,the energy saving rate and emission reduction rate of the technology in the material production stage reached 26.8%and 25.6%,respectively.During the construction phase,the energy saving rate reached 40%,and the emission reduction rate reached 35.7%.The measured data are consistent with the simulation results,which verifies its significant low-carbon performance.This technology provides a new technical path for the sustainable development of highway construction industry.
