	Abstract:Applying lower coherence interferometer executes scan of optic fiber sensor under different environmental state. Factors influence accuracy of results can be obtained through comparison between above tests, which are shown in details in this paper. Repeating test of optic fibers is completed as a part of calibration, an accuracy of 4 can be achieved as well. Data acquisition and data analysis are accomplished by the software of Labview. Installing reference point on signal arm to eliminate the deviation of initial scan time and reduce the error of lower coherence system.

	Abstract:Many cities in the world are located in basins. Basin can amplify ground motion significantly by the soft sediment, buried rock topography and edge effect in it. Hundreds of papers have been published on this effect for decades. Seismic waves are adopted as inputs in the analysis. Near field ground motion is governed predominantly by earthquake source. A hybrid source model is introduced in this paper, which combines Asperity model and K square model to take into account the physical nature and ignorance on the slip distribution on the faulting plane. The ground motion in short period range is synthesized by a random method in which dynamic corner frequency is applied in each sub-source model. The ground motion in the basin is further calculated by means of 1D equivalent linearization procedure. Two steps are carried out for the long period motion. Firstly, the displacement field at the top of buried crystal base rock surface is calculated by analytical Green Function method. Then the ground motion at ground surface is calculated by 3D wave propagation finite element method with input from the first step. The two parts of ground motion are finally superposed. For illustration, the result of a shallow basin from an earthquake with magnitude 6 on the blind fault beneath is shown and the distribution pattern of the response motion is summarized.

	Abstract:This paper describes a new meta-heuristic algorithm, called the harmony search (HS), which was conceptualized using the musical process of searching for a perfect state of harmony. The HS algorithm does not require initial values and uses a random search instead of a gradient search, so derivative information is unnecessary. This study focused on pipe diameter optimization while minimizing design cost, then compared the results of HS with genetic algorithm.The results are very promising and demonstrate the usefulness of harmony search algorithms in solving this kind of optimization problem.

	Abstract:Abstract: The wave impedance theory of reflection wave method and its localization were introduced. The FE models of diameter-extended piles and integrated piles with a hard soil layer surrounded were built. The wavelet transformation figures of the sampling point’s acceleration were studied when these two models were different in bug’s diameter and soil’s elastic modulus respectively. It was found that when the sampling frequency was bigger than 40 KHz, a group of wave crests in high frequency between the reflected wave of bug and the pile toe could be select to be the distinguishing character between these two models. The results can be a reference in the practice and provide a target in the inversion of the characteristic wave.
