摘要:在以框架结构建筑物为主的大城市,由深开挖引起的地层运动可能会潜在地导致建筑物的损坏。一个包含不均匀沉降和框架尺寸两个重要参数的新损伤图已经被提出,并在新加坡的捷运建设中,通过对现场实测数据和已发表数据比较已经得到验证,该图可替代原有损伤图或作为补充参考。虽然框架尺寸可以直接测量,但是测量精度仍高度依赖于预测难度较大的建筑物沉降量。

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 the frame dimensions, has been proposed. The chart has been validated against published data and field measurements obtained during the construction of mass rapid transit (MRT 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.
