However, the available land for railway construction is very limited, therefore experts design the railway using a tunnel. Risk analysis in Railway projects with tunnel design is carried out to determine the most important type of risks. The results of this research show that the railway project with tunnel design has the same risks as railway projects with other designs, there are site risk and environmental risk. After finding the most important risk, use the Multiphase risk management method to manage this risk.https://www.arce.ir/article_96030_b3f3c10d1f68d9b350be3b04955c24dc.pdfPapyrus PressAdvance Researches in Civil Engineering2645-72291420191101Liquefaction Potential Hazard in South East of Khoy9189603110.30469/arce.2019.96031ENMehrdadBagheriM.Sc. of Engineering Geology, Department of Engineering Geology, Ahar Branch, Islamic Azad University, Ahar, IranRouzbehDabiriAssistant Professor, Department of Civil Engineering, Tabriz Branch, Islamic Azad University, Tabriz, Iran.0000-0002-1807-1945Journal Article20190912One of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. This phenomenon can cause great damages to underground structures and buildings and lifelines. Liquefaction resistance of soils can be evaluated by experimental and field tests. In this research, results of liquefaction potential evaluation based on standard penetration test (SPT) were proposed. Case study area is Southeast of Khoy city at West Azerbaijan province in Iran. In this study 18 boreholes was collected. With considering type of soils and ground-water table level liquefaction potential evaluated. Then, liquefaction potential index (LPI) assessed. Obtained results showed that almost more of 50% alluvium sediments deposits is included sand and silty sand. Also, liquefaction potential hazard with considering ground water table level is high.https://www.arce.ir/article_96031_99bffe5c0cc04801b932fb2c8f06f264.pdfPapyrus PressAdvance Researches in Civil Engineering2645-72291420191101Application of Artificial Intelligence Models to Estimate Discharge over Semicircular Weirs19319603210.30469/arce.2019.96032ENMajidNiazkar1Ph.D. of Civil Engineering, Department of Civil and Environmental Engineering, Shiraz University, Shiraz, IranNaserTalebbeydokhtiProfessor, Department of Civil and Environmental Engineering, Shiraz University, Shiraz, IranSaeidHosein AfzaliAssociate Professor, Department of Civil and Environmental Engineering, Shiraz University, Shiraz, IranJournal Article20190630Weirs are one of the widely used hydraulic structures for measuring discharge in open channels. This study applies two artificial intelligence models named artificial neural network (ANN) and genetic programming (GP) to predict discharge flowing over semicircular weirs with different openings including sharp and semicircular crests. The considered data base was selected from the literature. The results of AI models were compared with those of two empirical formulas, which have been developed based on the same data for this purpose. Four evaluation criteria were considered for comparing the estimated discharges. The results obviously indicate that GP outperforms others based on the considered criteria.https://www.arce.ir/article_96032_e882bacd5b8026fa8e0e4d99c1f86731.pdfPapyrus PressAdvance Researches in Civil Engineering2645-72291420191101Seeking the Effects of Land Use on Modal Shift of Automobile Commuters in Response to TDM Policies: Case Study of Tehran32419603410.30469/arce.2019.96034ENReyhanehSadat ShahangianAssistant Professor, Institute for Management and Planning Studies, Tehran, IranJournal Article20190530To reduce the number of private cars and respectively to decrease the side effects of congestion in central business districts (CBD) of metropolitans is one of the main purposes of implementing transportation demand management policies. This study uses a set of stated preference data to investigate the relationship between land use characteristics, five TDM strategies and modal shift from private car. The target group of the study includes commuters who often drive to CBD for work or study during the morning peak hours. Results reveal the effectiveness of some of the tested variables on the choice to give up driving.https://www.arce.ir/article_96034_7dda2cf38b7fb2f7e91e74595caf344e.pdf
