摘要:
针对大规模铁路路基横断面边坡措施设计场景,提出了边坡措施组合的概念,将不同边坡措施由路肩至坡脚/堑顶串联为一个边坡措施组合,并设置其匹配条件。通过与各横断面左、右侧的路基类型、路基高度、措施类型等条件的匹配,从边坡措施组合数据库后返回条件吻合的边坡措施组合,完成相关设计。该方法具有设计效率高、通用性强等优点,已在包银、沈白、潍烟、集大原等多条铁路中得到应用,助力铁路路基横断面边坡设计向数字化、智能化转型。该方法不限于铁路领域,也可对市政道路、公路等领域的路基边坡设计方法升级提供借鉴。
Abstract:
To design slope measures for cross-sections of large-scale railway subgrade, this study introduced the concept of a slope measure combination, which connects diverse slope management strategies from the shoulder to the slope toe or top of the cutting, accompanied by the establishment of matching criteria. By aligning these combinations with conditions such as the subgrade type, subgrade height, and measure types on the left and right sides of each cross-section, the methodology retrieved from a database of slope measure combinations those that satisfy the given conditions, thereby completing the relevant design. This approach boasts advantages such as high design efficiency and broad applicability, having been successfully implemented in multiple railway projects, including Baotou-Yinchuan High-speed Railway, Shenyang-Baihe High-speed Railway, Weifang-Yantai High-speed Railway, and Ulanqab-Datong-Yuanping High-speed Railway, facilitating the digital and intelligent transformation of designing slope measures in cross sections of railway subgrade. Not confined to the railway sector, this method also offers valuable insights for upgrading slope design approaches in subgrades of municipal roads and highways.
