Abstract

ABSTRACT As the awareness of environmental protection and safety becomes increasingly important in route design, it is crucial to emphasize line position optimization of mountain roads in sloped sections. In this study, we devised a combined optimization factor (F), which includes the displacement mutation factor (F 1 ), two types of energy mutation factors (F 2 and F 3 ), and the regional earthwork balance factor (F 4 ), to measure the optimization options. We then applied this combined factor to a rural road in Gansu Province, China, to calculate and compare the different line position optimization results according to numerical calculation models. This method allowed the selection of a better optimization option (b = 2.5 m) as the final result. From a short-term perspective, the proposed method can ensure the slope stability and balance earthwork quantities in mountain road sections, as well as promote environmental protection. In addition, this method can provide an optimization concept for long-term application to engineering practices.

基于边坡稳定性和土方平衡的山路线位置优化方法

随着环保和安全意识在路线设计中的重要性日益提高，重视山区坡道路段的线路位置优化显得尤为重要。在本研究中，我们设计了一个组合优化因子(F)，其中包括位移突变因子(f1)、两种能量突变因子(f2和f3)和区域土方平衡因子(f4)，以衡量优化方案。然后，我们将这一组合因子应用于中国甘肃省的一条农村公路，根据数值计算模型计算和比较不同的线路位置优化结果。这种方法允许选择一个更好的优化选项(b = 2.5 m)作为最终结果。从短期来看，该方法既能保证山地公路路段的边坡稳定性，又能平衡土方工程量，促进环境保护。此外，该方法还为长期应用于工程实践提供了一种优化理念。
