摘要：在主要建筑物为框架结构的城市地区，深开挖所引起的地层移动可能会导致建筑物破坏。本文提出了一个包括两个关键参数为不均匀沉降和框架尺寸的新破坏图表。该图表对已公布的数据进行了验证，并且在新加坡地铁（东北线）的建造过程中得到了现场测量数据。本文提出的图表可作为其他相似图表的替代或补充。图表的准确性高度依赖于建筑物沉降的预测，目前框架尺寸的测量较简单，而建筑物沉降的预测难度较大。

Key words: Excavation, Building damage, Settlement, Frame structure

Abstract: Ground movements caused by deep excavations may potentially lead to building damages in urban cities where the majority of buildings are frame structures. A new damage chart, with two key parameters of the differential settlement and frame dimensions, has been proposed. The chart has been validated against published data, and field measurements have been obtained during the construction of mass rapid transit (North East Line) in Singapore. The proposed chart can be used as an alternative or a supplement to other similar charts. Although the measurement of the frame dimensions is straight forward, the accuracy of the chart highly depends on the predicted building settlement, which still remains a challenge.
