河堤边坡重力式挡墙预应力锚索加固设计分析

Gravity Retaining Wall with Pre-Stressed Ground Anchors Stabilizing a River Slope

结合佛山市西樵镇江浦东路北侧河堤边坡原有钢筋混凝土挡墙的特点,以及工程地质、水文地质条件、周边环境,尝试采用预应力锚索加固成功案例,并通过监测钢筋混凝土挡墙后土体深层水平位移稳定分析,验证加固方法的合理与可行性,为类似工程加固设计方法提供借鉴。

The existing retaining wall for the river bank slope along the north side of the East Jiangpu Road in Xijiao Township, Foshan City is a cast-in-place reinforced concrete wall. The design of the new retaining wall considers the characteristics of the existing wall, subsurface geotechnical and hydrological conditions, the adjacent environments and the previous successful expe rience in the design and construction of the pre-stressed ground anchors in the area. During the construction, the horizontal movements of soils behind the retaining wall were monitored and the results verified feasibility of the design method.
