Our country, Mexico, is one of the 80 countries with the most irrigation infrastructure in the world, ranks seventh, although environmental difficulties such as overexploitation of aquifers, salinity and pollution affect irrigation areas. Taking into account the increasing concentration of boron in surface and groundwater and the need to treat seawater, which contains large amounts of this element, it is important to develop effective technologies for the removal of boron. Unfortunately, there is no simple and economical method for this task. The great difficulty in selecting this method is the fact that boron appears in water in several numbers of chemical compounds and its concentration varies from environmental conditions from one site to another. Treating water with high concentrations of boron will allow this resource to be used in agricultural crops It will be possible to obtain a water treatment design, in which a chemical procedure is established to remove boron by precipitation in batches so that the cost of the treatment is economic, the second purpose will be to obtain a calculation memory to determine the concentration of Reagents to be used once the initial concentration of boron is known.","PeriodicalId":131243,"journal":{"name":"2017 XIII International Engineering Congress (CONIIN)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122679144","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}

Vehicle load is the main live action acting on the superstructure of a vehicular bridge. To estimate the distribution of this charge in the structural elements, different distribution models are used, which in its simplicity, they have limitations and restrictions for your application. Examples of these are the Courbon method and its variations, Homberg chart, standardized methods as coefficients AASHTO (American Association of State Highway and Transportation Officials), AASHTO LRFD (Load and Resistance Factors Design), Communications and Transport Secretariat (SCT by its Spanish acronym) standards, OHBDC (Ontario Highway Bridge Design Code) y CSA (Canadian Standard Association). The standardized methods mentioned above are mainly governed by a D-value defined by the geometric and material configuration of the bridge, as well as the specification of design load, which correlates the particular effects in the elements of the superstructure of these systems from of an analysis global, with the effects generated by one wheel line of load applied to an element particular in a particular analysis of the element. The criteria governing the structural design of bridges in Mexico is currently proposed by the SCT standards. Which has the criteria used in the AASHTO standards as a basis, it was developed for the specific conditions of the USA. This paper analyzes the principles and peculiarities of the above criteria, and presents the results of an analysis carried out for a particular structure using different criteria while proposing a methodology for the development of a model of load distribution in these systems, considering the specific conditions of Mexico.","PeriodicalId":131243,"journal":{"name":"2017 XIII International Engineering Congress (CONIIN)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115971029","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}

For example, if a spill occurs or there is a leak of a pipe near where there is a building, the mechanical properties of the soil can be affected, causing economic problems or, in extreme cases, loss of life due to lack of stability in the structure. It is possible to take decisions if we know the behavior of the soil in contact with some contaminant. In Mexico, some works have been initiated that evaluate the physical and mechanical properties of the soil contaminated; however, this information cannot be generalized because each place has various soil formations. In this work, we present a study of a high compressibility clayey soil (CH) contaminated with diesel to evaluate its impact on the limits of consistency and the compressibility index of the soil. We found that the liquid limit decreased when the soil was contaminated with diesel. The results showed that in the consolidation process in the contaminated soil a decrease in the compressibility index of 19% compared to the soil with water.","PeriodicalId":131243,"journal":{"name":"2017 XIII International Engineering Congress (CONIIN)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133540023","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}
