Identification of Source Time Function for Train-induced Vibration of Underground Tunnels
The objective of this paper is to identify the dynamic source time function for the train-induced vibration of underground tunnels. Under the consideration of the gaps between adjacent slabs and the constraint from equal-spacing fasteners, the vertical force loaded by the moving train is modelled by a periodical source time function. Consequently, the induced vibration at any specified observat...
متن کامل3D Modelling of Under Ground Burried Objects Based on Ground Penetration Radar
There is a growing demand for mapping and 3D modelling of buried objects such as pipelines, agricultural hetitage, landmines and other buried objects. Usually, large scale and high resolution maps from these objects are needed. Manually map generation and modeling of these objects are cost and time consuming and is dependent on lots of resources. Therefore, automating the subsurface mapping and...
متن کاملModelling of ground-borne vibration when the train speed approaches the critical speed
When trains run on soft ground, large deflections of the track and vibration of the ground can occur when the train speed approaches the speed of Rayleigh waves in the ground. Modelling is helpful to understand and mitigate such critical velocity effects. Here, a three-dimensional time-domain model of a load moving on a track and ground has been developed in the finite element software ABAQUS. ...
متن کاملVibration Generated by Underground Railway Trains
The control of vibration generated by railways in tunnels is complicated by the dynamic interaction between tunnel and track. Conventional methods (floating slab track, ballast mats, under-sleeper pads) do not perform as well as might be expected and it is the purpose of this paper to explore the sources of error. The major factors which must be taken into account pertain to the three-dimension...
