为开展严寒地区路基边坡信息技术监测，提升安全风险监控，构建交通工程中的路基稳定性监测技术系统，以长春北湖精细化工新材料产业示范园交通工程为例，根据路基边坡材料与地质条件，采用极限平衡法分析了拟建边坡安全稳定性；在路基边坡满足安全稳定性要求的基础上，模拟车辆行驶路面过程中动荷载引起路基变形问题，分析路基边坡监测点沉降变化较大的区域与布设范围。结果表明，拟建工程路基边坡安全稳定性满足规范设计与现场施工要求；通过有限元软件对动荷载引起路基变形问题进行分析，明确了路基边坡监测点的布置区域；采用光伏发电技术对路基监测设备供电，实现清洁能源自给自足。

For the information technology monitoring of roadbed slopes in cold regions, improving safety risk monitoring, and constructing a roadbed stability monitoring technology system in transportation engineering. Taking the transportation project of Changchun Beihu Fine Chemical New Materials Industry Demonstration Park as an example, based on the materials and geological conditions of the roadbed slope, the safety and stability of the proposed slope were analyzed using the limit equilibrium method. On the basis of meeting the safety and stability requirements of the roadbed slope, the deformation problem of the roadbed caused by dynamic loads during vehicle driving on the road surface was simulated, and the areas and deployment ranges with significant settlement changes of the roadbed slope monitoring points were analyzed. The results show that safety and stability of the proposed project's roadbed slope meet the requirements of standard design and on-site construction. By using finite element software to analyze the deformation of the roadbed caused by dynamic loads, the layout area of the roadbed slope monitoring points was clarified, and photovoltaic power generation technology was adopted to supply power to the roadbed monitoring equipment, achieving self-sufficiency in clean energy.
