预应力锚杆格构梁在某公路边坡加固中的应用

Design of the Prestressed Ground Anchors with Concrete Grid Beams for Highway Slope Stabilization

通过分析某道路工程边坡勘察资料,获得了边坡的自然环境概况、水文地质条件、物理力学等指标,并根据边坡的具体特征,采用圆弧滑动法对代表性的边坡剖面进行稳定性研究,提出根据不同坡段的不同地质条件分段采用预应力锚杆格构梁支护的设计方案,达到了安全和经济的要求,可为类似工程提供借鉴。

This paper presents a pre-stressed ground anchor with grid beams for a slope stability mitigation design project of a highway slope at North Mengshan Road in Fuzhou City. The physiographic and topographic conditions, geological and hydro logical conditions as well as rock and soil properties are obtained throughout the field and laboratory investigations. The repre sentative sections are analyzed with circular sliding analysis method. The pre-stressed ground anchors with grid beams are se- lected as the cost effective solution to for the stabilization mitigations.
