Method for designing mix proportion of green high-strength geopolymer pervious concrete

The invention relates to the technical field of pervious concrete, in particular to a green high-strength geopolymer pervious concrete mix proportion design method, which is used for solving the problem of lack of a comprehensive and reasonable geopolymer pervious concrete mix proportion design method in the prior art. The method comprises the following steps: selecting a primary selection range of coarse aggregate particle size, water-binder ratio and designed porosity, selecting a plurality of water-binder ratios and designed porosity in the primary selection range, and further combining to form a plurality of groups of set mixing ratios; preparing a plurality of test blocks according to a set mixing ratio, and performing performance test to obtain a performance test data set; constructing a regression model of water permeability and compressive strength by using the performance test data set; constructing a compressive strength prediction model by using a sparrow search algorithm and a BP neural network, a
