利用数学模型预测超大直径泥水平衡盾构法隧道工后沉降

On Using Mathematics Model to Forecast Post-construction Settlement of Super-large Diameter Slurry Balance Shield Tunneling Method

工程建设中地表沉降是由多种原因产生的,大致可分为施工中产生的沉降和施工后产生的沉降两部分。在软土地区的隧道施工中,工后沉降占有较大比例,研究预测工后沉降具有重要的工程价值。通过实测数据与几种预测模型的比较,分析了不同模型的优缺点及其应用情况。

Ground surface settlement is appeared by several causes,and it can be divided into two parts: settlement during construction and settlement after construction.For tunnel projects in soft soil area,the post-construction settlement may possess more proportion;therefore,a study of settlement after construction has very important engineering value.By comparing some forecast mathematics models and actual data,advantages & disadvantages and application conditions of different models are researched in this paper.
