Abstract

Abstract: The early stage damage of simply-supported girder bridges with continuous slab-decks are duetomany unresonable factorsin design and construction．According to the finite element theory and applying ANSYS，the mechanical behavior of simply-supported sister briage with conluo11s slab-decks under weight ofthe asphalt concrete surfacing，live load and temperature variation has been analyzed nonlinearly．And some precautionary and improving Ineasurs are suggested accordingly

Key words: simply-supported gider brige, continuous slab-deck, early stage damage, non-linearity, FEA, improvement

摘要： 简支梁桥桥面连续构造的早期损坏，是由设计和施工中诸多不合理因素引起的。笔者根据有限元理论，借助 ANSYS工作平台，对简支梁桥桥面连续构造在沥青砼铺装层重量、活载以及温度作用下的受力状况进行了空间非线性分析，并依此提出了预防对策及改善措施。

To further study its influence mechanism and to solve the problem of limited accuracy of traditional prediction methods under multi-feature data conditions, a pavement skid resistance performance assessment model based on the fusion of Bayesian optimization algorithm (BOA) and extreme gradient boosting (XGBoost) was proposed. Firstly, specimens phalt mixtures of different gradation types were prepared. Friction data and 3D texture data of the specimen surface were respectively obtained by using a pendulum friction meter and a 3D laser scanning device. Secondly, the height, the wavelength and shape parameters were extracted to describe the texture structure, and the texture feature importance analysis was carried out to clarify the factors that significantly affected the skid resistance. Then, the optimal key parameters were improved by introducing of the model BOA-XGBoost and the prediction model of skid resistance performance was established. The research results show that compared with the comparative models, the proposed model has higher accuracy, with a correlation coefficient R2 of 0.890 6, which is 25.2%, 13.0%, and 15.1% higher than those of the comparative models, respectively. The proposed model can effectively correlate texture features with pavement skid resistance performance. [J]. Journal of Chongqing Jiaotong University(Natural Science), 2025, 44(6): 35-44.
