3种轨道结构下地铁引起多层住宅室内振动模拟与实测
Measurement & simulation on the subway induced ground-borne vibration in multi-story residence under three track structures
摘要
Abstract
Because the relationship of ground and structure is weakly coupling, the interaction between ground and structure can be neglected. The problem of tunnel-ground-structure modal can merely obtain the results of vibration frequency below 20 Hz was overcome. The ground-borne vibration was analyzed under DTⅢ-2 fasten-er, low vibration track and Vanguard fastener. Comparing the simulation results with the measured results, it can be find that the simulation results and measured results are consistent. By means of comparison of results of VLzmax and limit of the codes GB/T 10070 and DB31/740, suggestion was put forward that corresponding track structure should be adopted as vibration reduction measure in different vibration request regional. This study offers a refer-ence for subway transit department to make reasonable measurement to deduce the influence of ground-borne vi-bration in buildings.关键词
