浅埋黄土隧道地表沉降预估方法研究

Research on the forecast and evaluating method of floor surface sinking of shallow-buried loess tunnel

通过对地表沉降机理分析,应用解析法与数值模拟法对比的形式预测,对浅埋黄土隧道地表沉降问题进行了比较分析与研究,结果基本符合沉降槽分布与变化规律,有利于控制浅埋黄土隧道地表沉降与规避风险。

Through the analysis of the floor surface sinking mechanism, it makes a forecast with the comparison of analytical method and numerical simulating method. And it makes a comparative analysis and research of the floor surface sinking of shallow-buried loess tunnel. The result mostly complies with the laying and changing law of settler. It shows that this forecast method is helpful to control the floor surface sinking of shallow-buried loess tunnel and avoid risk.
