本文采用国内现行列车速度构架振动的实测资料和国外高速列车轮对横向荷载测试资料,根据随机振动能量理论[1],用能量方差σ2作为控制条件,随机模拟出了高速列车构架人工蛇行波,并初步验证了以此波作为高速列车-桥梁时变系统激振源的正确性.

The quasi-high-speed train and reinforced concrete multi-span box girder bridge are considered as an integral vibration system in analysis. In accordance with random vibration energy theory1, and by taking artificial hunting curves of the train frame as excitation source, vibrating responses with 99% probability of the train and bridge system are calculated when a quasi-high-speed train runs through the reinforced concrete multi-span box girder bridge respectively at a speed of 160 km/h and...

Flow prediction is an important item in the construction of rail transit. This article illustrates the objective and contents of the prediction, analyses the difficulties and risks, poses the essentials of the reliability evaluation, and proposes a fluctuation for the prediction. Based on the real situation, this paper establishes a theory of anti-risk design by analying the limitation and breakthrough of the risks in flow prediction, then puts forward some fitting and transferable measures to protest the risks, which can add the flexibility between the prediction and the operation capacity designed. The author holds that, for the operation in urban mass transit, it is beneficial to design by stages, especially to determine the train-frame and driving frequency in the initial-stage, the short-term as well as the long-term separately.
