Soil-structure Interaction in Subway Environmental Vibration Prediction
摘要
Abstract
The attenuation law of environmental vibrations caused by subway operation inside and outside buildings was studied,The parameter changes of various influencing factors were analyzed.With a brick-concrete hybrid structure building near the subway line as an object,the three-dimensional numerical model including tunnel,soil and building was established to analyze the vibration transmission attenuation.Various contact algorithms,such as Penalty Constraint method,Multi-Point Constraint method,and combination algorithm,were employed to analyze the contact problem between soil and building foundation.With the horizontal distance between tunnel and building,tunnel depth,and soil type in the model as the basic influencing factors,various working conditions were designed to study the coupling loss of vibration in soil-structure interface,and explore the law of indoor and outdoor vibration transmission loss for the building.The results indicate that the effect of various contact methods is slightly different in the frequency band above 10 Hz,but the difference is significant at low frequencies below 10 Hz;The vibration transmission loss characteristics inside and outside the building near the peak of the 1/3 octave acceleration level under different influencing factors are basically consistent with the transmission loss characteristics of the maximum Z vibration level,but there is no obvious variation law in other frequency bands.关键词
