Abstract

Abstract: Based on application of U-shape structure automobile passage，which is in Foshan City of Guangdong Province，to wet soft soil foundation，the structure construction and the methods of the soft soil foundation processing of the U-shape are introduced，and the main point about design of the engineering watertightness and drain is given.The calculation model of the U-shape structure in wet soft soil foundation is disacssed and the mechanics characteristics and deformation characteristics of that U-shape structure are analyzed when there is no anti-pulling out pile.Practice proves that the U-shape structure for coastland wet soft soil foundation is applicable，safe，economical and worthy of extending.

Key words: U-shape, elastic foundation, FEA, CFG pile, watertightness

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.
