Conduct a brief parametric analysis to show the potential of this approach in evaluating the effectiveness of mitigation measures for vibration and re-radiated noise. Methods: Estimate sound pressure levels generated in residential compartments as a result of train travel; analyze the coupled train-trail-ground-construction system; solve the acoustic part of the problem. Results: A numerical model based on the substructuring approach is considered. A measure to reduce the level of vibration and re-radiated noise inside the building has been studied, which consists in a continuous “floating slab-track” system, for which different values of the elastic mat stiffness under the slab have been considered. It has been found that the effectiveness of this measure comes from a positive combination of two essential factors: the frequency content of the response and the cutoff frequency assigned to each solution adopted. Practical significance: A comprehensive methodology for determining ground vibration and re-radiated noise caused by railway traffic is presented. The dependence is obtained, that the efficiency of reduction of vibration level and re-radiated noise inside the building, will be higher, if the solution with low cutoff frequency is applied and the response has the most significant frequency content at high frequencies.","PeriodicalId":273874,"journal":{"name":"Proceedings of Petersburg Transport University","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125331897","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}

Methods: Theory of measurement errors, least squares method, parametric adjustment method. Results: It is shown that digital levels of various manufacturers, although they are used to solve various geodetic problems, and the work of many authors is devoted to the study of the influence of various factors on the accuracy of the result obtained by them, but in real production conditions a number of such factors cannot be excluded, which leads to a deterioration in the accuracy of the leveling results. Practical recommendations for mathematical processing of leveling networks built by digital levels in the CREDO NIVELIR software environment are developed, non-standard types of settlement marks are proposed with an indication of the methodology for performing observations when using them. Based on the known dependence of the tilt angle of the digital level on the ambient temperature, an original method for its determination is proposed, including situations when the obtained value exceeds its compensation limits by the level software. It is shown that the conclusions obtained on the basis of the experience of working with digital levels make it possible to increase the accuracy of such work, as well as reduce their labor intensity, when monitoring the settlement of engineering structures. Practical significance: The conclusions and results presented in the article have been obtained on the basis of long-term control of the settlement of both engineering structures under construction and in operation and can be implemented by engineering and geodetic construction support.","PeriodicalId":273874,"journal":{"name":"Proceedings of Petersburg Transport University","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114446583","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}

Previously, we have already considered the impact of the US and Western European sanctions on the development of the transport complex of the Russian Federation [1]. Now we can draw some conclusions about the development of the situation and consider the following questions: what ways have been found to overcome a difficult situation; how has the economy of the transport industry changed in 2022 and the beginning of 2023; what prospects lie ahead of the industry in the future? Methods: Comparison of the characteristics of the state and development of various main types of transport industry in 2022 with the indicators of the previous period of 2020-2021. Results: It is shown that since the end of February 2022, after the start of the special military operation, the Russian Federation has been under strong pressure in the form of a number of sanctions, mainly from the United States and Western Europe. The sanctions have greatly affected the Russian transport complex: a shortage of spare parts for cars, the inability to import by rail and the closure of airspace. Currently , new details are emerging almost every day related to the introduction of additional sanctions, their consequences, as well as facts confirming the increasing resilience of the Russian transport industry to these sanctions.
