In engineering practice, random variable is often characterized by the probability distribution in a finite interval.
Since the finite interval is not judged by the mathematical infinitesimal but the engineering scales, it makes it easier for the expression of the process of random variable in blind number.

Study on dynamic response test of long span PC girder bridge under the operating conditions Xiaodong Chen 1, a ,Xiaping Liu1,b ,Zhuo Sun1,Kahong Cai1 and Hong Yang2 1College of Civil Engineering, Guangzhou University, Guangzhou,510006,China 2College of Physics and Electronic Engineering, Guangzhou University, Guangzhou,510006,China a632118309@qq.com, bliuxiaping@yahoo.com.cn Keywords: Vehicle Loads, Acceleration, Dynamic Deflection, Power Spectrum, Impact Coefficient, Test Study.
In this paper, the acceleration and dynamic deflection of background engineering was measured simultaneously without interrupting the traffic.The analysis on measured signal power spectral density analysis and bridges impact coefficient was done, and making the comperance between the calculated values and the finite element calculated value.The researchs can provide the basic data for study on the long span PC girder bridge health monitoring system development and bridge vibration signal separation technique.
Background engineering The background bridge is Pazhou Bridge located in Guangzhou.The main bridge is a long span prestressed concrete V-shaped rigid frame-continuous composite girder bridge, and the superstructure using single cell box prestressed concrete box girder.It’s total length is 570m,which span combination is 70+135+160+135+70m, as shown in Figure 1.
The comparative analysis between bridge deflection, the acceleration test data and finite element calculation value showed that the background engineering design load could meet the design requirements, and the bridge had a good operational status.The measured frequency is quicker than the finite element calculated frequency, with the power spectral density of frequency showing the same result.
