[7] introduce 10 machine learning algorithms to predict the quality of surrounding rock using measure-while-drilling (MWD) data (drilling parameters) obtained from five tunnels of the Zhengzhou-Wanzhou line of the high-speed railway project in China. Through comparative analysis, three machine learning models with better comprehensive performance among them are selected to establish the tunnel surrounding rock intelligent classification system by the drill-and-blast method. The results of this study create a solid foundation for the dynamic design and intelligent construction of tunnels. [PERSON] et al. [8] study the structural response of segments in different assembling positions and under the condition of asymmetrical propulsion exerted by jacks. By establishing a finite element model of segment assembly, they explore the interaction and stress concentration of unlooped segments under asymmetric stress in the synchronous propulsion and assembly mode. This study determines the assembly error control range of the synchronous propulsion and assembly mode applied in practical projects. [PERSON] et al. [9] carry out indoor direct shear tests to deeply study the influence of the compound bentonite slurry on the friction characteristics of the pipe-soil interface from two aspects: the slurry concentration and the slurry standing time. By analyzing the test data and phenomena, combined with the physical properties of the slurry, the influencing mechanisms of the concentration and standing time on the friction characteristics of the interface are revealed. [PERSON] et al. [10] establish a design optimization method for feet-lock steel pipes under two working conditions, including predicted large deformation and observed large deformation before the primary lining construction. The method is applied to the Yulinzi Tunnel, and the results show that the original design of the feet-lock steel pipes could not meet the requirements of the controlling settlement. The active bearing design can significantly reduce the amount of steel required and the engineering cost. [PERSON] et al. [11] adopt the Loganathan formula based on a virtual image principle to calculate a surface settlement trough without isolation piles. On this basis, Melan a solution in the semi-infinite plane based on elasticity is introduced to derive the ultimate surface settlement trough from the perspective of negative friction of pile edge. The applicability and reliability of the analytical and numerical solutions are verified by comparing field measured data, which have significant engineering guiding reference in analyzing real projects. [PERSON] et al. [12] propose a refined three-dimensional model considering bolts and other construction loads to study the effect of jack thrust angle change on the mechanical characteristics of shield tunnel segmental linings. Discussions are carried out on the displacement, deformation, and stress of the tunnel segments and the connecting bolts. According to the obtained results, final recommendations will be provided to control the jack thrust angle. The results in this paper provide novel insights into the effect of jack thrust on shield tunnels. [PERSON] et al. [13] analyze the impact of improvements in tunnel sidewall brightness on the lighting environment and visual characteristics of human eyes based on the lighting experiments when the tunnel sidewalls are decorated with two different types of materials and illuminated by LED lamps with five different color temperatures. The test results show that the tunnel sidewall luminance will increase if the energy storage and luminescent coating with high reflectance is decorated on tunnel sidewalls, and the pavement luminance increases with the increasing sidewall luminance. [PERSON] et al. [14] consider the influence of internal pore structure characteristics and matrix material properties of foamed concrete on the overall elastic modulus. Combined with the two-layer embedded model, an inclusion theory model of the elastic modulus of foamed concrete is established.
