The invention provides high-strength gel particles. The high-strength gel particles are prepared from the following raw materials: 0.1 to 15 weight percent of biomacromolecules, 5 to 50 weight percent of comonomers, 0.01 to 1 weight percent of organic cross-linking agent, 0.05 to 5 weight percent of nano cross-linking agent, 0.01 to 1 weight percent of initiator and the balance of water, the raw materials further comprise a chelating agent solution containing metal cations, and the concentration of the chelating agent solution is 0.01 mol/L to 2 mol/L. The invention further provides a preparation method of the high-strength gel particles. According to the gel particles provided by the invention, a multi-cross-linked gel network is constructed by introducing biomacromolecules, a comonomer, a nano cross-linking agent and the like, so that the strength of the gel particles after water absorption and swelling is enhanced. 本发明提供了一种高强度凝胶颗粒，由以下原料制备得到：生物大分子0.1～15wt％，共聚单体5～50wt％，有机交联剂0.01～1wt％，纳米交联剂0.05～5wt％，引发剂0.01～1
