摘要
既有路改扩建项目日已成为全球工程界的重点拓展领域,通过对斯里兰卡A09公路重建段特点和控制条件的分析,对长大规模的既有路改建项目所涉及的关键工程设计方案进行分析。在复杂建设条件下,应用多国不同专业规范,提出合理可行的道路加宽、中线拟合与优化、最小间隙法确定初步纵断面、竖曲线参数分析、路基衔接处理、特殊路面结构、交叉口转弯模型、中英两国荷载分析与应用、生态环保理念的应用等关键设计方案。
Rehabilitation and improvement of existing road has become a global focus in the engineering field. With analysis of the special features and controlled conditions of A09 road project in Sri Lanka, this paper studies the key several design schemes for long-large scale reconstruction projects. With reference to complex construction conditions and multinational design specifications, the thesis presents key design schemes in terms of road widening, center line matching and optimizing, defining initial longitudinal cross-section with minimum interval method, analyzing vertical curve parameter, subgrade connection, particular pavement structure, intersection turning model, analysis and application of structure loads specified by China codes and British codes, and ecological protection.
