摘要
真空预压法是加固软土地基的有效方法。目前对真空预压过程中地下水位的变化情况存在较大分歧，本文通过对现有关于真空预压过程中地下水位变化情况的观点进行总结分析，指出地下水位的定义对分析地下水位的变化的重要性，并对地下水位的变化原因进行了探讨，得出真空预压过程中地下水位只会产生下降，不可能不变或上升，故认为真空预压兼有降水预压的双重功效。在此基础上，分析了影响地下水位变化的因素，对真空预压实际工程中地下水位的量测方法作了讨论，指出非压力式的电极埋设法在实际量测过程中也会产生较大误差。
Vacuum Preloading is an effective method to consolidate soft soil-foundation. Now there is great divergence in groundwater level in vacuum preloading. The current study on groundwater level in vacuum preloading is analyzed, and the thesis points out that it is important to define groundwater level. According to the exploration of cause of groundwater level, it is concluded that it is only possible to decrease groundwater level while impossible to keep or increase during vacuum preloading, so vacuum preloading contributes to dewatering, based on which, influence factors of groundwater are analyzed, and some discussions are made to the measurement method of groundwater level in vacuum preloading in engineering, in which it is pointed out that using the electrode-buried method which is non-pressure may produce great errors.
