抗滑桩+扶壁式挡土墙联合支护的工程应用

Engineering Application of Combined Support Measures of Anti-slide Pile and Buttress Retaining Wall

某园建工程包含三阶景观墙,原山体边坡表面没有处理、填土没有压实,在雨水长期浸泡的情况下出现墙体开裂和倒塌等问题。由于场地有限而无法将填填土挖除、重填压实的前提下,采用了下部抗滑桩、上部扶壁式挡土墙的联合支护措施对该园建工程进行了修复,扶壁式挡土墙外形按景观墙设计,整个填土的下滑推力由抗滑桩和扶壁式挡土墙共同承担,目前该修复工程已完成,经监测完全满足规范要求,该设计成果对类似工程具有一定指导和借鉴意义。

A garden building engineering contains three order landscape wall, the original mountain slope surface is not treated and the filled soils are not compacted, so some wall cracks and collapse appear in the rain for a long time. Due to limited space, the filled soils cannot be compacted, and so the combined support measures of anti-slide piles and buttress retaining wall are adopted to repair this garden building engineering, the shapes of the buttress retaining walls are same to the original land scene wall, and thrusting stresses caused by the wh ol e filled soils arc jointly undertaken by anti-slida pile and buttressed retaining wall. The repair project has been completed, the monitoring data completely satisfy the standard requirement, and this de sign provides some guidance and reference for similar proj cots.
