The invention discloses spliced blocks with a curve modeling function. The spliced blocks comprise three types of block components of pore column elements, pore elements and column elements, wherein the pore column elements comprise main parts, single pore column parts and double pore column parts, the pore elements comprise main pore parts and double pore parts, and the column elements comprise double column parts, wide reinforced column parts and triangle parts; modeling is achieved through cooperation among the block components, the block components can be expanded and spliced along a straight line and can also be vertically crosswise spliced, be spliced with corners and be spliced in a curve model, and one or multiple types of the block components can compose a spliced block toy with the curve modeling function.
