| 摘 要： | 基于上海地区地铁隧道盾构施工引发的工程性地面沉降机理分析,采用数值分析和数学拟合方法,对盾构埋深、地层损失率、盾构半径和穿越土层性质等因素与地面沉降影响范围和最大沉降量之间的基本规律分别进行了深入的分析研究,给出了它们之间各自的定量关系式,并在盾构施工实例中进行了分析和验证。

| Abstract: | Based on analysis of the mechanism of engineering land subsidence induced by the shield construction in subway tunnel in Shanghai city,the regularities and relationships between shield depth,stratigraphic loss rate,shield radius,feature of soil and influence scope of land subsidence,the largest settlement value,were individually and deeply researched using the numerical analysis and mathematical fitting method.And the quantitative relations among them were given.Finally case study of shield construction was... |
