Making sand castle is one of the most popular activities on the beach.How to make a more stable sand castle model has become a hot issue.In this paper,the optimal three-dimensional sand castle model in different conditions is studied.Compared with other similar studies,our model is more convenient for people to understand and give a more intuitive feeling.We study the relationship between various geometry and structural stability by controlling variables.In addition,we also set up a wave erosion model to compare the stability through the fluid flow equation. In order to find the best sand water mixture ratio which can make the sandcastle foundation most stable,we found that the slurry and sand water mixture have similar properties ingeniously,so we used the slurry to establish the slurry model,and found the most stable sand water proportion by comparing the viscosity,thus also reflecting the properties of the sand water mixture,which helped us to draw a conclusion. As for the problem of the optimal three-dimensional geometric model in rainy days,we have established a rain erosion model based on hydraulics and sediment kinematics.We judge the anti rain erosion ability of the geometry by the size of sediment carrying rate,find the data of similar experiments with the help of data,and then draw the corresponding image with the formula,and obtain the conclusion.Then we use the knowledge of structural mechanics,hydrodynamics and other aspects to discuss the method of using other strategies to prolong the service life of Sandburg from multiple angles and dimensions. In order to facilitate the calculation,we use MATLAB software to help us solve the calculation problem better.Finally,we provide several improvement ideas for the optimization of the model and the realization method under each optimization idea,and give an objective evaluation and analysis of the advantages and disadvantages of the model.
