城轨交通运行引起环境振动的预测

介绍影响轨道交通周围地面振动的主要因素,振动预测模型方面的问题,详细论述国内外振动数学预测公式的研究现状及存在的不足以及对预测模型和公式发展的展望。目前模型和公式考虑的工况少,准确性不高,建议在以后的研究中考虑更多的工况,并结合更多工程实测数据修正计算模型。

Status of Prediction about Vibration Resulted by Urban Railway Transit

With the acceleration of urbanization process and improvement of quality of people’s life, there is a growing concern over the problem of ground and building vibration resulted by urban railway system. It systematically explains the main factors resulting in the vibration of the ground surrounding the railway transit, discusses vibration forecast simulation and other problems, and describes in detail the research state of foreign and domestic mathematical vibration predicting formula, and the deficiencies in current research, as well as the future of the predicting model and predicting formula： the current models and the formulas considered few work conditions, and is coarse, suggest later study considered more work conditions, and amendment computing models based of more measured data of actual projects.
