There are some problems in construction, such as inaccurate material parameters and unclear influence of shield operation parameters on ground settlement. Based on a water-rich sand layer shield construction diversion tunnel, an orthogonal experiment is designed by setting the index of ground surface settlement, and a three-dimensional numerical simulation is used to analyze sensitivity of different material’s parameter. Mechanical parameters of materials are inverted according to the observed settlement. The subsidence lines under different excavation pressures, different synchronous grouting pressures and different speeds of the shield are calculated. The result shows that the surface subsidence is most sensitive to the change of internal friction angle of sand layer. Increasing the internal friction angle of the sand layer and the elastic modulus of the lining will reduce the settlement. The speed of the shield has a great influence on the subsidence. Increasing the speed of the shield, the maximum settlement of the surface settlement curve will increase, and the width of the "settlement tank" will also increase. The maximum settlement and the width of "settlement tank" decrease with the increase of excavation chamber pressure or synchronous grouting pressure.

针对现有盾构施工中地层材料参数测量计算不准确、不同掘进参数对地表沉降影响难以评价的问题,依托某富水砂层盾构施工的引水隧洞,通过三维数值模拟,设计地表沉降为指标的正交试验,分析了不同材料参数的敏感性;此外,依据实测沉降,反演了材料的力学参数,并计算不同开挖仓压力、同步注浆压力和推进速度等盾构掘进参数下的地表沉降曲线。结果表明,砂层内摩擦角对地表沉降影响较大,增加砂土内摩擦角和衬砌弹性模量会减小沉降;盾构掘进速度对地表沉降影响较大,增加掘进速度会增加最大沉降量和“沉降槽”宽度,增加开挖仓压力或增加同步注浆压力会减小最大沉降量和“沉降槽”宽度。

针对现有盾构施工中地层材料参数测量计算不准确、不同掘进参数对地表沉降影响难以评价的问题,依托某富水砂层盾构施工的引水隧洞,通过三维数值模拟,设计地表沉降为指标的正交试验,分析了不同材料参数的敏感性;此外,依据实测沉降,反演了材料的力学参数,并计算不同开挖仓压力、同步注浆压力和推进速度等盾构掘进参数下的地表沉降曲线。结果表明,砂层内摩擦角对地表沉降影响较大,增加砂土内摩擦角和衬砌弹性模量会减小沉降;盾构掘进速度对地表沉降影响较大,增加掘进速度会增加最大沉降量和“沉降槽”宽度,增加开挖仓压力或增加同步注浆压力会减小最大沉降量和“沉降槽”宽度。

There are some problems in construction, such as inaccurate material parameters and unclear influence of shield operation parameters on ground settlement. Based on a water-rich sand layer shield construction diversion tunnel, an orthogonal experiment is designed by setting the index of ground surface settlement, and a three-dimensional numerical simulation is used to analyze sensitivity of different material’s parameter. Mechanical parameters of materials are inverted according to the observed settlement. The subsidence lines under different excavation pressures, different synchronous grouting pressures and different speeds of the shield are calculated. The result shows that the surface subsidence is most sensitive to the change of internal friction angle of sand layer. Increasing the internal friction angle of the sand layer and the elastic modulus of the lining will reduce the settlement. The speed of the shield has a great influence on the subsidence. Increasing the speed of the shield, the maximum settlement of the surface settlement curve will increase, and the width of the "settlement tank" will also increase. The maximum settlement and the width of "settlement tank" decrease with the increase of excavation chamber pressure or synchronous grouting pressure.
