| 摘 要： | 真空排水预压加固软土地基的效果很大程度上取决于真空度沿垂直排水通道的传递效果，尤其是深层软土的固结。分析比较了袋装砂井和塑料排水板的真空度传递损失以及损失的类型，指出局部损失要大于沿程损失，通水量大的塑料排水板传递真空度的性能要优于袋装砂井。

| Abstract: | The effect of the soft ground improved with vacuum preloading, especially the consolidation of deep soft clay ,depends on the transfer of vacuum along vertical drain path In this paper, the losses of vacuum during its transference along packed sand drains and plastic draining board are compared It is pointed out the vacuum transference in plastic draining board with large discharge capacity is better than in packed sand drains |

| Keywords: | vacuum preloading method vertical drain packed sand drains plastic draining board loss of transfer |
