Integrated Method of Vibration Reduction and Safety Precautions of Interchange Railway Construction in Soft Soil
Taking the engineering of subways crossing under railway lines in the littoral deposition area of Yangtze River Delta for example ,the processing method of sub regionally pre-reinforcing foundation step by step is presented and the field measurements of vibration in reinforced and non -reinforced area are conducted. The effect of vibration reduction and isolation in reinforced area and the propagation laws of ground vibration after reinforcement are analyzed in two ways , which are time history of acceleration and 1/3 octave vibration level. The results show that ground stabilization around railway lines can effectively reduce the environment vibration caused by train , especially for the low frequency.
