| 摘 要： | 从巴隆的等垂直应变方程组出发，结合真空堆载联合预应法的特点，建立了真空堆载联合预压的渗流模型，给出了渗流的基本方程及其解析解。同时，结合公路路基分级施工的特点，推导出分级加荷条件下的渗流量计算公式，应用该公式可以核算真空泵配置的台数，推求地下水位下降量和渗透水压随深度的变化。为进一步降低抽真空用电量提供了依据。并以一工程实例加以验证，算例表明计算值与实测值较为吻合。

| Abstract: | Based on Barron's co vertical formulas, a seepage model for the vacuum surcharge preloading method is developed, and a seepage equation and its analytical solution are given. In combination with the characteristics of subgrade construction in stages, a formula is deduced for calculation of seepage under the condition of loading in stages. With the formula, the number of vacuum pumps needed is checked, and the decrease of groundwater table and variation of seepage water pressure with depth are calculated, providing a basis for further decrease of electric power consumption in vacuum pumping. An example shows that the calculated result is in good agreement with the measured result. |
