The membership degree is used to express fuzzy characteristics of information. An uncertain linguistic variable is used to express linguistic descriptive characteristics of information. A ranking model for construction project risk factorsis proposed to identify the main risk factors on the basis of the interval grey fuzzy uncertain linguistic set and the continuous interval argument ordered weighted averaging (C-OWA) operator. We take the Weft Three-Road Cross-River Tunnel in Nanjing as a case to verify the feasibility of the proposed model.. Research results show that compared with fuzzy sets that can only use membership degree to express fuzziness, the interval grey fuzzy uncertain linguistic set can express the grey, fuzzy, and linguistic descriptive characteristics of practical construction project risk information simultaneously. The proposed model based on the theory helps to improve the comprehensiveness and authenticity of risk information expression, as well as the accuracy of risk factor rankings. The results of this work could assist project managers in determining main risk factors and thereby provide a theoretical basis for taking pre-control measures.","PeriodicalId":288169,"journal":{"name":"Journal of Highway and Transportation Research and Development","volume":"151 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131096783","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 framework of coarse-grained soil was analyzed, and the SEEP/W module of software Geo-studio was used to calculate the change in matrix suction, underground water table line, and seepage gradient. Then, the calculation result for seepage was imported into FLAC3D using FISH language, considering the change in underground water table line, matrix suction, and seepage force. The influence of seepage force on the stability of the slope was also analyzed. Results showed that rainfall affected the spatial distribution of the underground water table line, matrix suction, and seepage gradient. The underground water table line lifted gradually from the foot of the embankment slope and developed into a deep slope. After a rainfall, the underground water table line decreased rapidly and the height of the final line near the embankment center was higher than the initial state. The matrix suction dissipated gradually because of the change in the underground water table line but recovered slowly when the rainfall stopped. At the beginning of a rainfall, the positive values of X-direction seepage gradients turned to negative and the negative areas expanded gradually. The plastic zone of the slope extended gradually from the foot to the inside of the slope as the rainfall continued. After the rainfall, the plastic zone mainly occurred at the foot of the slope. The slope safety factor increased gradually at the beginning of the 24 h period. The safety factor decreased rapidly and reached the minimum after 72 h. Then, the rainfall safety factor was gradually restored, but the recovery of the safety factor was delayed and smaller than during the initial state.","PeriodicalId":288169,"journal":{"name":"Journal of Highway and Transportation Research and Development","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116036936","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}

To effectively reconstruct the anti-cracking performance of high viscoelastic tar sands, a semi-circular bending test was performed to measure the maximum load and fracture energy. The test results show that when the test temperature remains constant, the maximum failure load of the specimen increases along with loading rate, while the fracture energy of the specimen decreases along with increasing loading rate. Meanwhile, when the loading rate remains constant, the maximum failure load of the specimen decreases along with increasing temperature, while the fracture energy increases along with temperature. The test device is simple and cheap, while the test specimen is easy to manufacture. Therefore, the semi-circular bending test can be used as a standard method for testing the crack resistance design of asphalt mixture. A parameter sensitivity analysis is also conducted by using the ABAQUS finite element numerical simulation method. The experiment and numerical simulation results are compared to verify whether fracture energy can be used to evaluate the anti-cracking performance of high viscoelastic tar sands.","PeriodicalId":288169,"journal":{"name":"Journal of Highway and Transportation Research and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131321463","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}
