摘要

煤场挡土墙基础对地基的承载力要求较高,在天然地基承载力或变形不能满足上部结构要求时,一般要采用人工方法对地基进行强化处理。本文结合工程地质及现场效果,对不同的地基处理方案进行了技术经济分析,综合认为预制方桩比振冲碎石桩复合地基经济,技术上更为优化,为类似场地挡煤墙基础地基处理积累了工程经验。
        The retaining wall of coal yard needs a high requirement of foundation bearing capacity. When the bearing capacity or the distortion of natural foundation can not meet the design's requirement, foundation treatment usually can be taken to strengthen it by hand. According to the engineering geology and the actural site conditions, the different schemes for strengthening the foundation were introduced through technical and economic analysis. The results showed that the precast square pile is better than the vibro-replacement stone column, which could accumulate engineering experience for retaining wall foundation treatment in similar sites.
