Introduction

Not all ground traffic systems can cause ground-induced vibration and/or ground-induced structural noise. The rail traffic system vibration is by It is the most common and most important vibration source in the operation of the steel wheel on the rail. All types of rail transit systems produce geostrophic and/or ground induced structural noise (especially in urban areas) The environment has a negative impact. It is therefore necessary to evaluate the geostrophic vibration and building response at different distances from the vibration source. When there is the following demand, This section can be used to guide the relevant planning. Build or rebuild the railway, build or rebuild the building; The dynamic performance of the track changes or the dynamic characteristics of the train change; Train operating conditions change (such as the total length of the train, train speed or operating mode changes); Evaluation of vibration mitigation measures. The correct prediction of ground-induced vibration and/or ground-induced structural noise is an important part of the assessment, including the identification of new or converted rail systems The impact of vibration on existing buildings, or the impact assessment of new buildings adjacent to existing rail transit systems. building The standard [and/or limit] of the ground-induced vibration and/or ground-induced structural noise is the second part of the assessment. But the standard and limit Generally by the national standards and other international standards. The prediction of ground-induced vibration and/or ground-induced structural noise caused by rail transit systems is a complex and evolving technical field. this Some of the basic ideas of the forecasting model are defined to ensure their applicability to the objectives and the consistency of their methods. The guide is used to correct and confirm the model and verify its feasibility, which is an important step in quantifying and improving the accuracy of the model. Table 1 shows the framework for each stage for the construction or reconstruction of the rail transit system, or the rail transit system along the alteration of the building. Headquarters We give general referral and guide. A more detailed section will be given in the subsequent criteria, whose title names are listed in the preface.

1 Scope

This part of GB/T 33521 specifies the ground vibration generated by the operation of the orbital system and the resulting ground induced structure in the building General requirements for noise. This section lists the factors and parameters that need to be considered and gives guidelines for forecasting methods applicable to different environmental conditions (eg, In addition to the assessment of the impact of indoor personnel and sensitive equipment in buildings, can also be used for risk assessment of structural damage to buildings). This section requires attention to the following. --- vibration source characteristics. launch (such as trains, wheels, rails, rails, rail support structure); - propagation path. propagation (such as earth conditions, distance); --- vibration by the building. incoming (such as basic, architectural form). This section covers all wheel and rail systems from light rail trains to high-speed trains and cargo trains. This section gives the ground lines, elevated Structures and tunnels. This part does not involve vibration caused by the construction and maintenance of the track system, does not involve air noise, nor does it involve an important impact on the environment Structural noise caused by overhead structures.
