To solve this problem, rock mechanics tests are needed to study the mechanical properties of coal seams and top and bottom plates. In this paper, triaxial compression tests were applied to the No. Coal-two seam and top and a bottom slab of Wangjiazhai coal mine, and the compressive strength, residual strength and cohesive force C, and internal friction angle of coal rocks under different circumferential pressure were measured. φ values. The test results show that the residual strength of the rock is higher than that of the coal sample and decays faster with the increase of strain, and the axial bearing limit of the coal rock is generally linear with the surrounding pressure, which generally conforms to Coulomb's strength criterion. The findings of the study are of great significance for the support design of the roadway and the study of other reinforcement mechanisms.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125448861","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}

During the construction of civil engineering, there is no scientific and reasonable supervision system for the supervision of construction, which greatly affects the quality of engineering and the control and management of engineering cost. In this paper, through the application of DT (Decision tree) algorithm, the research of civil engineering cost prediction is carried out. Aiming at the application of the algorithm in civil engineering cost management, this paper tries to improve the C4.5 algorithm. DT civil engineering life-cycle cost analysis and prediction model is trained by training set, and the optimal result of civil engineering life-cycle cost analysis is obtained by inputting sample data for model prediction. The application results show that the above algorithm has lower computational complexity and higher prediction efficiency in civil engineering cost prediction, which can better meet the needs of actual civil engineering cost analysis and prediction.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125047112","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}

While brilliant achievements have been made in industrialization, China's environmental problems have become more and more prominent. Therefore, under the current trend of building transformation, prefabricated construction will become an important way for the civil engineering industry to achieve high-quality development. Wood structure has a long history in China. As one of the application forms of prefabricated buildings, wood structure has been widely used in developed countries. In recent years, the application of wood structure in prefabricated structure has also been widely concerned in scientific research and application fields in China. This paper mainly focuses on the research of wood structure, namely, the performance and processing of new materials, the performance and innovation of components, the research and development of system, and the connection performance and progress. Through these studies, the research trend of wood structure for the application of prefabricated buildings in the future is explored, which can provide reference for future research work and prospect the application progress of wood structure in prefabricated buildings.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130289126","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}

Because the bridge span is large, so because of weather, war and other reasons when the damage, can only be set up pontoon repair. Limited by hydrological conditions and other factors, the disadvantages of emergency repair of pontoon bridge are very obvious, among which the disadvantages of difficult operation and low traffic speed directly limit the overall emergency repair progress. Therefore, the bridge bearing based on hydraulic control in this paper can control the adaptive bearing to actively compensate and adjust with the help of the rapid calculation of the calculation system without blocking the channel, so as to greatly improve the passage efficiency and reduce the cost of emergency repair.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125908339","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}

Through the structural improvement of the traditional column conical cyclone, a spiral wall cyclone suitable for secondary sorting of lead-zinc tailings is proposed, and the lead-zinc tailings with different density are quickly separated by using the diversion of the spiral wall and the enrichment of mineral particles. The results showed that the recovery rate of heavy concentrate PbO increased from 55.55% to 85.25% by the spiral wall cyclone after structural optimization, an increase of nearly 30%, and the enrichment ratio of down-export PbO concentrate also increased from 1.321 to 1.762. It can be seen that the optimized spiral wall cyclone can effectively increase the secondary sorting efficiency of lead-zinc tailings, and provide a reference for the structural design of hydraulic cyclones in the same type of mine to a certain extent.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122375058","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}
