Therefore, accurately understanding the dynamic changes in the infiltration characteristics of embankments is of great significance for judging and evaluating the stability of engineering. This study conducted indoor model experiments and used ground penetrating radar to detect the phreatic lines of soil. By comparing the radar detection results with the measured position of the phreatic lines, it was determined that the phreatic lines appeared as a continuous strong reflection surface with similar shapes in the radargram, and the reflection below the reflection surface became weaker. Through time-domain analysis of the single waveform at different time points, it was found that the amplitude of the reflected wave at the saturation line was larger, and the energy attenuation below the saturation line was faster, resulting in a rapid decrease in amplitude; perform Fourier transform on a single channel signal to obtain a spectrogram, and perform frequency domain analysis on it. The main frequency is around 600MHz, and the second main frequency is around 900MHz. As the saturation line rises, the main frequency gradually shifts towards lower frequencies.","PeriodicalId":355471,"journal":{"name":"Advances in Engineering Technology Research","volume":"3 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141266817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As for the relationship between the weathering degree of cultural relics surface and the type, ornamentation and color of glass samples, the weathering degree and the type, ornamentation and color of glass samples were corresponding to unilateral factors, and the relationship was preliminarily explored by bar charts. It was concluded that the weathering degree had a certain multiple relationship with the three indexes. In order to further study the relationship quantitatively, we used the correlation thermogram to analyze.

To classify ancient glass types, we used the BP neural network classification prediction model to train, and the classification rules obtained depended on the difference of chemical composition content, and we tested the places where there was an accuracy dispute between the two. The classification of subclasses is based on the index evaluation using the method of hierarchy-entropy weight-coefficient of variation. The chemical components of potassium oxide and lead oxide are used to subclassify different ancient glass types.

The water quality of the entry has a higher demand for investment and occupying a vast land. High maintenance expenses, high water quality after treatment, and other issues exist. In this study, the oily spray paint wastewater was treated using an electrochemical and Fenton process, which has a high oxidation capacity, a fast oxidation rate, and a wide application of the characteristics of the Electro-Fenton process used in the pretreatment of spray paint wastewater. This study focuses on the electrochemical optimization and improvement of the Fenton technique, and it employs Fe2+ and H2O2 generated by the electrochemical approach as a continuous source of Fenton reagent. Simultaneously, electrode-related oxidation may destroy organic matter, effectively reducing the concentration of organic matter in spray paint wastewater, and when paired with the traditional Sequencing Batch Reactor Activated Sludge Process (SBR) operation treatment mode, offers a comprehensive process idea. While improving the efficiency and quality of spray paint wastewater treatment, the cost should be kept as low as feasible in order to provide effective reference schemes for spray paint wastewater treatment, allowing for future study.","PeriodicalId":355471,"journal":{"name":"Advances in Engineering Technology Research","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140430557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
