| 摘 要： | 基于砂井地基固结理论的基础，建立了关于袋装砂井地基的3个非理想因素的非理想综合参数，利用解析方法，提出了用图表法来计算袋装砂井的间距值，制出了理想井与非理想井井径比用表。并用此方法对广东西部沿海高速公路新会段软基处理段的袋装砂井间距进行了计算，得出了既经济又合理的间距值。

| Abstract: | On the basis of on the consolidation theory of sand drain foundation, nonideal combined parameters of well resistance, smear action and hydraulic condition are created. The chart method to calculate sand-wick space is prt forward by analytic method in this paper.Taking the soft foundation treatment test part in Xinhui Section in west coastal expressway in Guangdong Province as an example, the economical and reasonable well spacing using the above method are calculated. |
