The flexural test was carried out with rectangular specimens of 400 mm in length, 100 mm in width and 100 mm in height, 3 specimens per experimental group, 45 specimens in total. After the specimens were cured for 28 d, the mechanical properties were tested according to CECS13:2009 \"Test Methods for Steel Fiber Concrete\". The results showed that the mechanical properties of steel fiber concrete were significantly improved compared with those of ordinary concrete, with a maximum increase of 11.5% in compressive strength, 49.0% in flexural strength and 45.6% in splitting strength. This paper analyzes the relationship between the volume rate of steel fiber and the mechanical properties of concrete through the test results, and proposes the relationship curve equation of the effect of volume rate of steel fiber on the mechanical properties of concrete, which can be used as a reference for engineering design.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"248 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":"116055649","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}

Among them, the urban heat island effect has seriously affected the sustainable development of society. Therefore, from the perspective of mitigating the urban heat island effect, this study uses two phases of remote sensing images of Chengdu in 2002 and 2019 as the main data. Using the methods of supervised land use classification and surface temperature inversion, the spatial and temporal changes and characteristics of land use and surface temperature in the central urban area of Chengdu are analyzed. The effects of different land use types on the surface temperature are also explored to investigate their thermal environmental effects. The main research results are as follows: (1) the area of construction land in the central urban area of Chengdu increased greatly from 2002-2019, and the proportion changed from 12.4% to 41.2%; the area of cultivated land and forest land decreased significantly. (2) The high-temperature area was mainly concentrated in the central region from 2002 to 2019, and the area was increasingly expanded; the low-temperature area shifted from the original northwest region to the eastern and southern regions. (3) Land use change was significantly correlated with the thermal environment. Surface temperature was negatively correlated with NDBI and positively correlated with NDBI.","PeriodicalId":441364,"journal":{"name":"Academic Journal of Architecture and Geotechnical Engineering","volume":"55 3 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":"124867907","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}
