摘要

根据抽真空时加固区内真空渗流场的形成机制和变化特点，把真空渗流场的形成过程分为非稳定渗流和稳定渗流两个阶段。利用渗流量计算公式，计算加固区内渗流量随时间变化过程曲线。结合两个阶段加固区地下渗流场的变化特性，分别利用Theis和Dupuit计算模型计算不同时刻的地下水位，并用实测进行验证。

Abstract

According to the formation principle and change characteristics of vacuum seepage field in the reinforced zone during vacuumizing

the formation process is divided into two stages

unstable seepage stage and stable seepage stage. Different seepage discharge calculation formulae are used

and the curve of seepage discharge is obtained. According to the change characteristics of underground water dynamics

the THEIS model and DUPUIT model are used to calculate the groundwater level of different time.
