摘要： 为了准确预测由高层建筑引发土体应力场和渗流场变化而导致的地面沉降，以比奥固结理论为基础，结合土体非线性流变理论，将比奥固结理论中的本构关系拓展到黏弹塑性，并考虑了土体孔隙度、渗透系数及变形参数随有效应力的动态变化关系。以河北省沧州市为例，建立了沧州市高层建筑荷载、地下水渗流与土体变形三维流固全耦合数学模型。在对模型进行识别、验证的基础上，模拟预测了沧州市在地下水停采、仅存在高层建筑荷载的影响下，从2010年12月底到2025年12月底逐年的各含水层组地下水流场变化特征和地面沉降发展趋势。结果表明：沧州市由高层建筑荷载引发的最大地面沉降量为40.57 mm，最大地面沉降速率为2.7 mm/a，位于沧州市区。

Abstract: In order to predict the land subsidence accurately caused by high-rise building which led to the changing of stress field and seepage flow field, the constitutive relation was extended to viscoelastic plasticity based on Biot's consolidation theory and combined with the nonlinear rheological theory of soil, and the dynamic change relationship of mechanical parameters and hydraulic parameters were also took into account. A three-dimensional full coupling mathematic model of Cangzhou combined with high-rise building load, groundwater seepage and deformation of soil settlement was set up. Based on identification and verification of the model, the characteristics of each aquifer groundwater flow field and developing tendency of land subsidence from the end of December 2010 to the end of December 2025 was predicted with the condition that exploitation of the groundwater in the study area was stopped. The results show that:the maximum of land subsidence caused by high-rise building in Cangzhou is 40.57mm, and the maximum rate of land subsidence is 2.7 mm/a, locate in the urban district of Cangzhou.

Key words: high-rise building load, land subsidence, Biot's consolidation theory, groundwater seepage, three-dimentional full coupling math model, Cangzhou, Hebei Province
