摘要
针对注浆加固顶升工程中普遍存在的回沉现象 ,初步分析了其产生的原因 ,认为是粘土 -浆液的流变性所引起的 ,本文采用粘弹性反演分析方法对隧道的回沉量进行了计算和预测 ,并结合一实际工程对现场施工进行了预测和指导 ,取得了很好的效果。
The re settlement of tunnel during ground treatment by grouting is preliminarily analyzed in this paper. The rheology of grout before coagulation is regarded as the main cause. The re settlement is calculated and forecasted by viscoelastic back analysis. This method has been applied to a practical engineering project and proved to be effective and valuable.
