摘要:
以西安地铁四号线挖掘机器人施工为背景，探讨机器人荷载与临时仰拱跨度对临时仰拱安全性的影响。数值模拟与静力分析结果表明：在现有临时仰拱设计参数下，引入小型挖掘机器人不会对结构的安全性造成显著影响。若使用更大荷载机器人，可能会造成临时仰拱的垮塌，甚至工作面的塌方，须对临时仰拱重新予以设计。基于研究结果，建议加强参数，如增大工字钢截面、提高钢材和混凝土强度等级、加密加粗混凝土板底部构造筋、加设上部负筋、或采取铺设临时钢板等措施。为类似隧道工程引进挖掘机器人的安全生产提供理论指导。
Abstract:
Based on the robot excavation in Xi’an Metro Line Four, the investigation to the effect of robot construction on safety of temporary inverted arch is performed. Results of static studies and numerical analysis show that the introduction of a small robot would not pose a threat to the safety of temporary support structures. In order to increase the construction speed, the utilization of a robot with greater load may cause failure of temporary inverted arch, or even collapse of tunnel face. So temporary inverted arch needs to be reinforced. Finally, suggestions are provided to improve safety, such as increasing cross-section of I-beam, raising strength grade of steel and concrete, adding the upper negative reinforcement, spreading out temporary steel plates, etc. This paper could provide useful guidance for similar engineering.
