Description
Summary:The strength of a sandcastle is closely related to its shape and material.We developed a sand castle model of optimal sand-to water mixture proportion.The collected data were used to fit the regression linear equation and the statistical regression model was used to analyze the optimal water-sand ratio.Based on the sensitivity analysis, the consistency between the model and the reality is verified, and the robustness of the model is also verified.After the general shape of the sand castle is determined, the sand castle shape is optimized and adjusted taking the influence of rainfall into consideration.Based on the relationship between soil slope and infiltration rate and erosion rate,we divided the rainwater erosion sand castle into two stages: infiltration effect of different slopes on water-sand ratio and slope effect on erosion rate after water content saturation.After obtaining the optimal slope angles of two stages, the optimal precise 3d geometry was evaluated by AHP with the stability parameters and two slope angles.
