In this paper, based on the random simulation method, three joint distribution beach stability monitoring stations are established. Combined with the Gibbs sampling method, the random simulation of the three stations is realized. By comparing the measured and simulated beach stability, the effectiveness of the simulation prediction is checked. The coastal stability assessment technology and more than 1 year of field data observation are used to analyze the coastal stability. From the observed random simulation data, it is shown that there is a completely stable equilibrium position on the bank and beach during the survey period, and there is no large erosion and deposition. According to the existing data and analysis results, it is found that the beach stability is still in a certain dynamic equilibrium. For the beach slope, the slope of the water part of the inclined surface is more obvious in the natural embankment than in the artificial concrete embankment and the artificial bath; the slope of the sloping surface is almost the same as that of the natural embankment, the slope of the artificial concrete, and the slope of the artificial beach. The import product manual is responsible for transmitting information, so that consumers can accurately and intuitively understand the basic knowledge and indicators of food, which is the reason for consumers to buy food. At present, there are some mistakes in the English translation of imported product instructions in terms of language, function, and culture. This paper analyzes these mistakes with examples and gives corresponding improvement methods, so as to make consumers stay away from the misunderstanding of imported products and promote product sales.
