摘　　要：为评价振动沉管挤密碎石桩对软土地基的处治效果,文中采用原地监测试验对比分析处治后软土地基的沉降量、沉降速率、水平位移、侧向位移等。结果表明,碎石桩桩体质量良好,振动沉管挤密碎石桩施工工艺可行、质量可靠。In order to evaluate the performance of vibration sinking gravel compaction pile, this paper compares the detection data of typical cross sections, including settlement, settlement rate, horizontal displacement and lateral displacement. Experimental results indicate that the gravel pile has excellent performance. Therefore, it is feasible to use this method to reinforce the soft soil in practical project.
