高层建筑物荷载与地下水开采叠加作用下的地面沉降特征
CHARACTERISTICS OF LAND SUBSIDENCE DUE TO BOTH HIGH-RISE BUILDING AND EXPLOITATION OF GROUNDWATER IN URBAN AREA
摘要
Abstract
The distribution of land subsidence caused by both high-rise building loading and exploitation of groundwater is increasingly complex in urban area. This paper examines the land subsidence in Tanggu area. It considers the equilibrium condition, the elastic constitutive condition, the deformation compatibility condition of solid, and the continuity condition of water flow in soil consolidation. It then develops a three-dimensional land subsidence model for Tanggu area. The model is also based on the Biot's consolidation theory and takes into account both high-rise building loading and exploitation of groundwater. The finite element method is applied to the numerical calculation of the ground subsidence. The results indicate that there will be a considerable ground settlement in 3 ～ 4 years after construction of high-rise building. The settlement under the condition of both high-rise building loading and the exploitation of groundwater is lower than the sum settlement under he two single conditions. The model has a good convergence property and its computing results conform to actual data well.关键词
