摘要： 以不同类型高速公路岩土边坡为研究对象，考虑边坡三维精确地形、开挖地层、工程措施、监测设施、桥隧隧道、地下水位等多元信息，提出基于风化地裙和岩层界面地层模型的综合三维建模方法和可视化分析技术，在数据库平台的基础上，建立高速公路沿线边坡的信息分析系统，介绍了该系统在福宁高速公路滑坡和及其他典型边坡中的应用，对公路边坡地质条件、施工开挖与加固、监测信息等综合分析提供有效的技术支撑平台，也对同类工程具有借鉴意义。

Abstract: The stability of different types of highway slopes are studied by considering the three-dimensional topography; soil strata to be cut, construction measures; instrumentation probes; effect of highway bridges and tunnels; as well as groundwater table. The threedimensional visualized slope analysis information database was established by based on the weathered zone and soilrock interface along highway alignment. The paper introduces the application of the databased in the mitigation of landslides along FuNing Expressway. The database provided the information platform that integrating the highway geology, slope cut and construction as well as monitoring.
