Zhao, Y.; Zhang, D.; Du, X., and Xiong, B. 2018. Simulation on variability of marine geotechnical parameters based on data reconstruction. In: Ashraf, M.A. and Chowdhury, A.J.K. (eds.), Coastal Ecosystem Responses to Human and Climatic Changes throughout Asia.

A data reconstruction method for the variability of marine geotechnical parameters is proposed in this paper. By changing the variogram, the spatial variability of the random field of the geotechnical parameters is quantitatively described, and the random field of the geotechnical parameters is discretized. According to the multidimensional and efficient numerical quadrature theory, the mean of the response specific function is calculated. By means of the fast Fourier transform numerical probability analysis method and the maximum entropy distribution, the total probability distribution of the response quantity is solved, which is used to quantitatively estimate the variability of marine geotechnical parameters. Simulation and practical data show that this method has the advantages of high accuracy and high computational efficiency.
