地铁上盖建筑振动特性及参数敏感性研究
Vibration Characteristics and Parameter Sensitivity of Subway Overlaid Buildings
摘要
Abstract
To analyze the vibration influence on the overlaid buildings caused by the operation of the subway depot,a track-soil-cover plate-overlaid buildings coupled model was established based on the overlaid buildings of a subway depot.The vibration transmission characteristics of the overlaid buildings under the conditions of varying operating speeds,track structures,foundation soil properties and parameters of the overlaid buildings were investigated.Consequently,the important parameters affecting the vibration of the overlaid buildings were determined,and their parameter sensitivity analysis was car-ried out.The results show that the train speed has a greater influence on the vibration of the upper floor than the change of track structure parameters.The difference of foundation soil conditions will significantly affect the vibration characteristics of the overlaid buildings,which is mainly determined by the shear wave velocity of the soil layer.Compared with the elastic modulus of the upper cover slab and the section of the upper cover column,the thickness of the upper cover slab has a great-er influence on the vibration of the overlaid buildings,and increasing the thickness of the upper cover slab can effectively re-duce the vibration amplification effect of the incident wave reflection on the top layer of the upper cover.The thickness of the upper floor slab exhibits the highest sensitivity to the vibration of the overlaid buildings,followed closely by train speed.The research results may provide a reference for the selection of structural design parameters of subway overlaid buildings and the subsequent vibration isolation design.关键词
