At first, the formwork erection elevation and pre-camber of the bridge in each stage, as well as stress values of key cross-sections were determined by simulating the whole construction process using the finite element software. Then, the design parameters were identified and the model was corrected by field data collection and considering various influencing factors, so as to ensure effectiveness of the model. Finally, the formwork erection elevation was adjusted according to the stress and altitude in each construction stage, followed by closure of the bridge. According to field monitoring and adjustment, the measured alignment and stress of the bridge conform to the design and the error meets the requirements of specification, indicating a favorable monitoring effect. The research can provide reference for construction of similar bridges.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"161 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":"114511691","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 AE real-time monitoring techniques and macroscopic crack observations, the crack evolution mechanism of the cracked specimens during deformation and damage was investigated. The results show that there are three stages of microcrack incubation, macroscopic crack extension and cracking damage during SCA crushing. The tensile stress is 0.06-0.1 times of the compressive stress when brittle materials such as rocks are subjected to SCA leading to cracking damage. A large number of AE events with small amplitudes and a small number of AE events with large amplitudes represent that macroscopic cracks are generated by the rapid aggregation of a large number of microcracks before they are slowly formed. The cracking is usually done by first connecting adjacent holes into lines and then extending to the free surface. The direction of static crushing and the cracking effect can be controlled by designing the borehole location and free surface distribution.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"64 6 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":"123445408","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}

Base on the mechanical performance test of short-cut basalt fiber concrete, the influence of fiber content and fiber length on split tensile strength, flexural strength, and shear strength of basalt fiber concrete were discussed in this paper. With the increase of short-cut basalt fiber content, the split tensile strength and flexural strength were respectively increased by 13.3% and 16.9%, but the shear strength of basalt fiber concrete specimens was lower than reference concrete specimens. With the same fiber content, the monofilament length of short-cut basalt fiber was increased, the shear strength recovered to the level of reference concrete. When the fiber content was 0.1% and the length of the fiber concrete specimens was 12mm, the split tensile strength of the fiber concrete specimen was 13.3% higher than that of the reference concrete specimens. According to the test results, increasing the content and length of fibers could effectively improve the tensile properties of concrete materials.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"22 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":"114428735","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}
