Pseudo-analytic Solution to Random Displacement Field Around a Circular Opening

This paper studies the analytic principle of random displacement field in a stochastic materials,focusing particularly on the random displacement of a circular opening in geologic materials with random elastic properties. A pseudo-analytic solution is deduced, including the expression of random displacement and its statistic characteristics. The study results clearly indicate that the random displacement is not only related to the properties of the parameter of stochastic media, but also to the space position in the stochastic field.
