摘要

为了预测盾构隧道施工引起的地表横向沉降，针对狮子洋隧道陆地段DIK42+660断面地层，通过理论分析，利用Peck公式对该断面地表横向沉降量进行计算；通过数值模拟，利用ANSYS建立地层的有限元模型，并从数值模拟结果中获取地表单元的横向沉降量；最后通过与现场监测结果对比，对理论分析和数值模拟的地表横向沉降量预测方法进行评价。研究结果可为盾构隧道地表沉降的预测提供有效的方法。

Abstract

In this paper, the transverse ground surface settlement of DIK42+660 crosssection of land section of Shiziyang tunnel induced by shield boring is calculated by means of Peck formula The ground is numerically simulated by means of ANSYS finite element model, and the transverse ground surface settlement values are obtained from the numerical simulation results The transverse ground surface settlement values obtained by means of theoretical analysis and numerical simulation respectively are estimated by means of comparing them with the measured values The paper can provide reference for the prediction of ground surface settlement of shieldbored tunnel of similar projects in the future

Key words： shieldbored tunnel; ground surface settlement; theoretical analysis; numerical simulation; field validation
