| 摘 要： | 合肥—六安高速公路工程第一至第二合同段,共有弱膨胀土25×104m3,其性质较差,直接填筑存在工程隐患,但对其进行石灰改良处理后可用于路基填筑,其中经石灰改良之后用于路基的为22×104m3。避免从外借土填筑,直接节省投资300多万元。论文介绍用石灰改良处理弱膨胀土的施工质量管理。

| Abstract: | There is 250000m3 weak expansive soil within the first and second contract sections of the Hefei-Lu’an Expressway project,which is poor in nature,cannot be directly used for filling of roadbed before lime treatment of it.The improved soil totaling 220000 m3 has been used in the project,saving 3 million yuan investment.This paper introduced quality control of the process in which weak expansive soil is treated with lime |
