本文的目的是研究开挖过程中地表的沉降特征。选取台北市10个施工质量和现场观测资料较好的开挖实例，研究其开挖行为特征。根据实际开挖实例，确定了最大侧向墙体挠度的位置、最大侧向墙体挠度的大小、最大侧向墙体挠度与地表最大沉降量的关系、最大地表沉降量的位置和视差影响范围。最后，提出了一个经验公式来预测开挖中心断面的地表沉降量分布，该区域的变形特征可能是平面应变。
The objective of this paper is to study the characteristics of ground surface settlement during excavation. Ten excavation cases in Taipei with good-quality construction and field observation data are selected to study the characteristics of excavation behavior. The location of maximum lateral wall deflection, magnitude of maximum lateral wall deflection, relationship of maximum lateral wall deflection and maximum ground surface settlement, location of maximum ground surface settlement, and apparent influence range are thus established based on the actual excavation cases. Finally, an empirical formula is proposed to predict the ground surface settlement profile at the center section of an excavation, where the behavior may be characterized by plane-strain conditions.
