摘要： 结合阳江市北山公园危岩现状的特点，以及地质、施工、周边环境条件，分析危岩产生的机理。在景区首次提出一种新型浅埋式格构钢筋混凝土支撑+钢管桩加固设计方法，对支撑及钢管桩力学性能进行了力学复核计算，并通过监测危岩位移稳定分析，验证了新方法的合理与可行性，具有一定理论与工程实用意义，为类似工程加固设计方法提供了有益的经验。

Abstract: This paper presents a new design method for the remediation of a rolling rock mass at Beishan Park of Yangjiang City. Factors that might affect the stability of the rolling rock mass, such as, geological conditions, construction methods and adjacent environments, are investigated. A new design method for stabilizing the rolling rock mass by using the combination of shallow buried reinforced concrete grid beam support system and steel pipe piles. Both strength of both the supporting beams and the pipe piles are checked. The displacement of the rolling rock mass was also monitored during and after the construction and the results are satisfactory. The case study has proved that this new design method is appropriate.
