In the waters of the bridge area, more and more ships pass through, and the navigation environment is more complex than that of the ordinary channel. For the staff of the traffic management department and bridge maintenance, it is necessary to always pay attention to the behavior of passing ships and remind the ships with abnormal behavior to prevent accidents that damage the bridge. Firstly, by analyzing the collision risk of ship bridge and the abnormal behavior of ship itself, this paper combines the two to obtain the judgment standard of ship abnormal behavior in the waters of bridge area; then, considering the small sample problem of ship abnormal behavior in the actual data, a large number of ship trajectory data are generated by the method of ship motion equation and random data generation. Based on the generated ship trajectory data, the identification model of ship abnormal behavior in the bridge area is established by using BP neural network classification method to give early warning of ship abnormal behavior, Provide technical means for the safe passage of ships in the waters of the bridge area to reduce or avoid the losses caused to the bridge.","PeriodicalId":425834,"journal":{"name":"2021 7th International Conference on Hydraulic and Civil Engineering & Smart Water Conservancy and Intelligent Disaster Reduction Forum (ICHCE & SWIDR)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133207087","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}

In order to improve the structural integrity, keyways are often provided on the joint surface to compensate for the enhancement of the joint surface shear resistance and improve the structural integrity. In the design of high arch dams, the application of spherical keyways on the transverse joints are more and more widespread. Due to the huge workload of simulating the spherical keyway densely distributed on the joint surface, there are few related results that accurately simulate the transverse joint keyway and truly reflect the force transmission characteristics of the keyway of high arch dams during earthquakes. In order to study the force transmission characteristics of the spherical keyway in the high arch dam during the seismic process, this paper proposes a parametric simulation modeling method for the high arch dam considering the spherical keyway of the transverse joint, and establishes the foundation-water-dam dynamics considering the spherical keyway. The calculation model uses high-performance parallel computing technology for calculation and analysis. The relationship between the high stress area of the keyway surface and the opening of the transverse joint, and the force transmission characteristics of the location of the maximum shear stress in the high arch dam during a strong earthquake are studied in detail.","PeriodicalId":425834,"journal":{"name":"2021 7th International Conference on Hydraulic and Civil Engineering & Smart Water Conservancy and Intelligent Disaster Reduction Forum (ICHCE & SWIDR)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131946535","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}

Then the “Support Vector Machine” algorithm is applied to classify the feature data extracted by each algorithm. By this way, the accuracy and efficiency of the three algorithms under different parameters are compared. The test comparison results show that the Hog algorithm is more efficient but the accuracy is average, the LBP algorithm has the highest accuracy but the efficiency is general when multiple training is required, and the Haar algorithm has the relatively lowest accuracy and efficiency. The results can provide a basis for the selection of different algorithms and parameters for various scenarios where the visual inspection and recognition system of un-vibrated concrete may be applied.","PeriodicalId":425834,"journal":{"name":"2021 7th International Conference on Hydraulic and Civil Engineering & Smart Water Conservancy and Intelligent Disaster Reduction Forum (ICHCE & SWIDR)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133860664","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}

Based on the model box test of soil nail drawing, this paper studies the displacement field of anchorage body in the process of soil nail drawing and analyzes the displacement field along the length of anchorage body and the vertical of anchorage body, respectively. The results show that before reaching the critical state, the deformation of the soil around the anchor decreases along the drawing point to the bottom of the anchor under the same load. However, when the anchor reaches the ultimate load, the pull-out failure curve of the anchor bolt does not change from an increasing trend to a stable horizontal trend, showing a curve form of low at both ends and high in the middle.","PeriodicalId":425834,"journal":{"name":"2021 7th International Conference on Hydraulic and Civil Engineering & Smart Water Conservancy and Intelligent Disaster Reduction Forum (ICHCE & SWIDR)","volume":"160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123022257","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}

When different grouting widths and depths are used, The maximum settlement value of the petroleum pipeline is compared and analyzed. It is recommended that the grouting width is 3.05m and the grouting depth is 4.5m.
