A bearing capacity estimation method for bridge piles was developed. In this method, the pulse echo test was used to select the intact piles; the dynamic stiffness was obtained by the impulse transient response test. A total of 680 bridge piles were tested, and their capacities were estimated. Finally, core drilling analysis was used to check the reliability of this method. The results show that, for intact piles, an obvious positive correlation exits between the dynamic stiffness and bearing capacity of the piles. The core drilling analysis proved that the estimation method was reliable.

A statistically based microzonation tool for delineating zones within a region most susceptible to strong spectral amplification of earthquake accelerations in the 2 to 4 Hertz range is introduced using detailed Modified Mercalli Intensity (MMI) surveys and surface geology. A rationale for the research method is discussed using four arguments: the Fourier spectral analysis of earthquake ground motions and the spectral response method; an empirical versus a theoretical justification, low cost, and a consideration for previous research into the topic specific to the area of the case study chosen.
