In this paper, using the orthogonal design method, 16 groups(96 pieces) of shear masonry specimens were designed. According to the results of the experiment, the effects of the mortar strength, kind of walling materials, the mixed quantity of PVB and MC for the shear resistance of masonry specimens have been analysed. By way of experimental statistical regression, the calculating formula of the shear strength of modified mortar masonry for every kind of walling material has been established.

At the same time, 9 groups data are conversely choosed according to uniform orthogonal array from 71 groups observed data of suspended grid plunge pool, the mold is set up by the method of PPR, the surplus 62 groups data are used to proceed examination, the empirical type optimum design of experiments are proceeded inversely, all of these confirm that a lot of model experimental results can be replaced by a few of test times under nonstrict uniform experimental condition. The result can provide the feasibility reference basis for same kind of model design of experiments in future.
