英文摘要	This paper focuses on the solute transport characteristics of karst water tracing and its engineering application by numerical simulation and analysis of field tracer curves. First, the computation models and simulation methods of solute transport are proposed. Then, five kinds of representative geological models of karst water tracing are built, and seven cases of solute transport are studied. Solute transport characteristics in the straight pipeline model, bend model, depression model, waterfall model, and branch pipeline model are analyzed. The solute mass fraction affected by the pipeline width, flow velocity, bend radius, depression depth, the number of bends, depressions, and waterfalls are discussed. Finally, the numerical results are applied in actual tracer tests for analyzing the groundwater connection medium. Some preliminary laws and conclusions are obtained as follows: (1) The peak of solute mass fraction decreases gradually with the bend radius, pipeline width, flow velocity, the number of bends, depressions, and waterfalls rising. (2) The influence of depression depth on the tracer curve is little. (3) The time to peak increases gradually with the number of depressions and waterfalls rising, while it decreases gradually with the increase of flow velocity. (4) The distribution of the tracer curve widens gradually with the number of bends, depressions, and waterfalls rising, while it narrows gradually with the increase of flow velocity.
