摘要
强夯置换法在软弱地基加固中得到广泛应用,如何应用其挤密效应进行桩基纠偏未见报道。以某高边坡桩柱式挡土墙为背景,介绍采用强夯置换法进行桩基纠偏的处理方案、参数估算方法及施工质量控制要点等。实践表明,在周边环境条件允许的情况下,只需要合理设置碎石约束墙体,就可以得到较好的纠偏效果。
The dynamic replacement method was applied widely for the soft soil treatment, at present, there is not report about how to take advantage of its extrusion effect to rectify pile deviation. Take a retaining wall of a high slope for instance, this paper introduces the treatment scheme and parameters calculating method of the dynamic replacement method in deviation rectification of support pile. The result shows that this method is effective which only needs a proper gravel wall layout if the surrounding condition is satisfied.
