| 摘 要： | 井阻作用影响地基的固结速率，排水带的通水量与井阻作用有直接关系，过小通水量的排水带在地基中产生较大的井阻，通水量较大的排水带又使生产成本提高。笔者分析了通水量对地基固结的影响，并提出根据被加固地基的性状来选择通水量的方法。建议用公式 来确定所使用排水带的容许通水量下限值。

| Abstract: | The well resistance affects the rate of consolidation of treated ground, the discharge capacity of prefabricated vertical drains relates directly to the well resistance; the smaller discharge capacity, the more well resistance; but the more discharge capacity, the more costs of prefabricated vertical drains. In this paper, the effect of consolidation due to the discharge capacity of vertical drains is analyzed; and the method for selecting the discharge capacity of prefabricated vertical drains for different treated ground is given. It is suggested that the discharge capacity of prefabricated vertical drains satisfying 2shw23.5HFkq= can be the criteria whether to consider the well resistance or not. |

| Keywords: | weak ground prefabricated vertical drains discharge capacity well resistance |
