Abstract

ABSTRACT The Ten Arches Bridge is a historical stone bridge that is located in Amman, Jordan. The bridge has a valuable cultural heritage as it was built in 1908 to serve the Hejaz Railway Line. This study presents a structural assessment of the bridge including a field inspection, experimental investigation, and numerical structural analysis. The study also investigates the efficacy of utilizing in-situ Non-Destructive Testing (NDT) such as Rebound Hammer (RH) and Ultrasonic Pulse Velocity (UPV) tests in the assessment of stone arch bridges. Detailed experimental and numerical investigations were performed to identify the structural integrity of the bridge by evaluating the acting stresses and displacements under static and dynamic loads. Minor deteriorations were found in the bridge’s body due to human and environmental factors. However, the geometrical properties of the bridge have not been significantly changed. The obtained results of the numerical analysis concluded that the bridge can sustain the current imposed dead and traffic loads, but not serve seismic actions. Compressive strength and modulus of elasticity of stone units obtained by RH and UPV tests are in agreement with the laboratory tests. Accordingly, NDT techniques can provide and verify basic mechanical properties that are needed for numerical analyses.
约旦历史悠久的十拱桥的结构评估
摘要十拱门大桥是一座历史悠久的石桥,位于约旦安曼。这座桥建于1908年,为赫贾兹铁路线服务,因此拥有宝贵的文化遗产。本研究对该桥进行了结构评估,包括现场检查、试验研究和数值结构分析。该研究还调查了利用原位无损检测(NDT)(如回弹锤(RH)和超声波脉冲速度(UPV)测试)评估石拱桥的效果。通过评估静态和动态载荷下的作用应力和位移,进行了详细的实验和数值研究,以确定桥梁的结构完整性。由于人为因素和环境因素,桥体出现轻微损坏。然而,该桥的几何特性并未发生显著变化。数值分析结果表明,该桥能够承受当前施加的恒载和交通荷载,但不能承受地震作用。通过RH和UPV测试获得的石材单元的抗压强度和弹性模量与实验室测试一致。因此,无损检测技术可以提供和验证数值分析所需的基本机械性能。
