复式真空预压加固技术离心机模型试验及现场试验的实现周 杰 1，刘飞禹 1摘要：真空预压在工程中的应用愈来愈多，但在工程中存在排水板於堵、后期抽水效率下降、深层加固效果差强人意等等问题。因此展开了大量的室内试验，由于模型试验尺寸过小测得的数据与现场实际数据相差较大，并不能准确反映现场实情。因此近几年开展了真空预压离线模型试验，试验数据表明试验可基本模拟现场试验，得到较为准确的数据，但同时也存在边界沉降难测定、真空荷载施加过程难模拟等问题。本文对复式真空预压加固技术离心机模型试验的实现进行了探讨，并对目前国内外现场试验的进展进行了归纳和总结。GIh6xDT。BuFJlJL。关键词：离心模型试验；真空预压；絮凝剂；中图分类号：TU43 文献标识码：A 文章编号：1000–4548(2025)10–1807–095jNRuzF。qpmnKp1。作者简介：刘飞禹(1976–)，男，博士，2000 年毕业于中南大学地质工程专业，现任副教授，主要从事加筋土及土动力学方面的教学与讨论工作。E-mail：IqhchLP。vAGAAcy。The centrifuge model testof Vacuum preloading technology miYmlMn。ZnS7s3E。Zhou Jie1, Liu Feiyu1Abstract: The technology of vacuum preloading is applied in engineering more and more frequently, but there are plenty problems, such as clogging of drainage board ,thedrop of pumping efficiency in late stage, pore efficiency in deep strengthening.Therefore a large number of laboratory testsare launched, due to the small size of the model test data we can not get the data accuracy enough So in recent years some scholars carried out the centrifuge model test of vacuum preloading, test data shows that can be basically simulated field tests to obtain more accurate data, but there are also have some problems as the difficult determination of the boundary settlement, and vacuum load simulation application process. In this paper, to achieve the centrifuge model test of vacuum preloading technology were discussed, and the progress of the current test are conducted and summarized.wZxRYiw。VWczJjw。Keywo...
