The traditional manual management method is difficult to adapt to the increasing number of ship engineering projects, which seriously hinders the development of the enterprise. It is essential to manage the project side scientifically, standardly and reasonably. Based on the problems existing in the ship engineering project management center, this paper demonstrates how to apply information technology to the project management process based on the SQL Server database for data organization and system development. By considering system requirements from the bottom up, and considering data requirements from the top down through life cycle design, a general model containing ship product data is developed. The system can ensure that the correct data is provided to the user at the right time and in the correct form, making the entire ship engineering project proceed more smoothly. It solves the problems of cluttered project information, difficult information integration, and chaotic process management. It realizes the functions of electronic management of ship engineering projects, unified management of initial data, and online pro-cessing of business processes, which improves management efficiency and reduces management costs.","PeriodicalId":285594,"journal":{"name":"2020 International Conference on Urban Engineering and Management Science (ICUEMS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116345139","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 modernization of Wuchang city, Baisha Sandbank became a “test field” for Zhang Zhidong to establish the national industry in the early stage. The process of urban planning and construction was affected by the nationalist thought of “national salvation”. This article uses historical documents, historical maps, and cadastral maps to analyze the evolution of Baisha Sandbank's urban morphology during three periods: “sandbanks ashore, the period of Zhang Zhidong's New Deal (1861–1911)”, “transdockation developments, the early industrialization of the Republic of China (1912–1937)” and “the period of Anti-Japanese War, development stagnated (1937–1949)” The conclusion shows that the change of geographical environment is the basic condition for the evolution. Policy guidance, factory construction, and transdockation development in different periods are the main driving forces for morphological evolution. The evolution of urban morphology reflects the modernization of Baisha Sandbank from the late perspective of nationalist urban construction, and is evidence of the process from late-exogenous modernization to active modernization, and the changes in urban structure and social culture.","PeriodicalId":285594,"journal":{"name":"2020 International Conference on Urban Engineering and Management Science (ICUEMS)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114814752","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}

The objective is to study the characteristics during excavation in Beijing and fill in the blank on the scenario. Thirty excavation cases with good-quality construction and field observation data are selected to quantify the relationship between settlement and excavation, and to analyze the ground surface deformation behavior. The magnitude and location of maximum ground surface settlement ($delta vm$), the apparent influence range, development process and pattern are depicted. This study demonstrates that: (1) Concave trough pattern of final ground surface settlement is detected, slight heave was observed and $delta vm$ located at distances about 0.5H to 0.75H from the wall. (2) Spatial difference of ground surface settlement ($delta v$) varies greatly, great depression appeared behind each wall and maximum settlements at midspans of both sides occurs with the lowest 1-2 struts removal, especially the long side with a $Delta delta v$ of $2.8 pm 0.75$ mm. Movement was least of all by the corners. (3) Final settlement generally ranges from 5mm to -20mm, less than $delta vm$. Influence zones reach to a distance about 2.5H to 3.1H outside the excavation.","PeriodicalId":285594,"journal":{"name":"2020 International Conference on Urban Engineering and Management Science (ICUEMS)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126257234","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}

The aim of the research work is to investigate the characteristic impact of 12mm and 25mm basalt length on the flexural strength of cement-based materials. According to the distribution of basalt fibers in mixed media, the random distribution of basalt fibers in the entire beam and the distribution in half of the beam were analyzed. Flexural tests were carried out on the beams using the three-point test set-up. From the analyzed result, it was noted that the flexural capacities recorded increased noticeably as basalt fiber was introduced. 2.5% of 12mm basalt fibers yielded the highest flexural strength of 6.962N/mm2 in the category of when the basalt fiber is randomly dispersed in the entire volume of the beam. Also, beam-reinforced fiber only at the tensile zone yielded higher flexural strength compared to when the fiber was randomly distributed at both the compressive and tensile zones. 1.5% of 12mm length that occupies the tensile zone only, yielded a flexural strength of 8.57N/mm2 as against the cement-based mixture with no basalt fiber (3.147N/mm2).","PeriodicalId":285594,"journal":{"name":"2020 International Conference on Urban Engineering and Management Science (ICUEMS)","volume":"AES-12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126524705","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}
