Abstract

The vibration effect of subway train operation on the adjacent building structure has become one of the outstanding problems in the development of urban underground rail transit and the construction facilities along the line. The new technology of intelligent interconnection provides new ideas for the analysis of the impact of subway vibration, but the network edge side faces many challenges such as connecting massive heterogeneous devices and real-time business. Therefore, in this article, based on the needs of actual projects, on the basis of edge computing technology, through the field measurement and numerical simulation methods, the typical subway adjacent building structure is affected by the vibration of subway train operation. Edge computing solves the urgent need to realize the function of cloud computing at the edge equipment of massive subway networks, and provides active support for the analysis of the vibration impact of subway train operations on adjacent building structures. Practical case analysis and vibration impact assessment illustrate the superiority of the realization of edge analysis-based metro operation on the vibration analysis of buildings along the line. This method can provide scientific reference and basis for the exhibition of modern subway technology.

Highlights

With the rapid development of the current industrialization, the city is gradually expanding in size, the population continues to increase, and the road traffic conditions in large cities are seriously deteriorating
INFLUENCE OF SUBWAY OPERATION ON VIBRATION OF BUILDINGS ALONG THE LINE Urban rail transit is an ideal means of transportation with large volume, safety, speed, punctuality, convenience and comfort
In terms of image recognition, the processing time of the server is increased by 50 ∼ 100ms, which can improve the recognition accuracy of 10% ∼ 20%, which means that without improving the existing recognition algorithm, by introducing mobile edge computing technology, you can The identification effect is improved by reducing the transmission delay between the server and the mobile terminal [26]

Summary

INTRODUCTION

With the rapid development of the current industrialization, the city is gradually expanding in size, the population continues to increase, and the road traffic conditions in large cities are seriously deteriorating. Jolles C J C et al Studied the vibration problems caused by train operation in railways and tunnels using the finite element-boundary element coupling model [11]. On the basis of the theory of vibration generated by subway operation, combined with new technologies such as edge computing, an analysis model of the impact of subway operation on buildings along the edge is constructed. This method can provide scientific reference and basis for the development of modern metro industry
