This dissertation is devoted to the Hausdorff dimension for a type of disc Besicovitch sets. It is well known that the situation of R2 about Kakeya problem has been solved. There exist several methods which can prove it. One of those methods to R3 space is generalized in this paper. It is proved that there are a type of disc Besicovitch sets in R3 whose Hausdorff dimension isR3.
