<p>This study is based on the background that the tunnel of Ningbo Metro Line 8 passes beneath the tunnel of Line 1. A three-dimensional numerical model was developed using Midas to simulate the deformation induced by the construction of the new Line 8 tunnel beneath the existing Line 1 tunnel. The results show that the maximum lateral horizontal deformation, longitudinal horizontal deformation, and vertical deformation of the Line 1 tunnel occur after the excavation of the Line 8 tunnel is completed. Notably, all deformations comply with the settlement control standards for existing tunnels in urban rail transit systems in China. After the excavation of the Line 8 tunnel is completed, the maximum surface settlement is less than the settlement control value, indicating that the excavation of Line 8 tunnel has less additional impact on the Line 1 tunnel. It is recommended that, during the construction of the new tunnel, intensive monitoring of the existing tunnel is implemented, particularly focusing on settlement in the central section, to mitigate the risk of structural damage due to excessive deformation.</p>

<p class="04-abstract" style="margin: 0in 0in 12.0pt 0in;"><span style="font-size: 10.0pt;">This mixed methods sequential explanatory study explored how computational thinking influences elementary students' attitudes by engaging the students in coding a music composition with an autonomous robot. Pre and post tests were used to document students’ attitudes toward music composition and coding over the course of six weeks. Eighty fifth-grade students participated in the music composition project, coding for one hour each week in an engineering class. The students were randomly organized into four study groups: individualized, collaborative, traditional, and Use-Modify-Create (UMC). Findings indicate that students experienced a significant increase in positive attitudes toward music composition after the robotics coding activity. Both the individualized and collaborative groups reported enhanced enthusiasm for music composition, while the UMC group showed increased positivity towards coding and greater confidence in their coding abilities. These results suggest that music educators can enhance student attitudes toward both computational thinking and music composition by integrating robotics into the music curriculum. The main contributions of this study include: (1) empirical evidence of positive attitude changes toward music and coding through robotics; (2) comparative analysis of four instructional modes; and (3) a practical framework for integrating robotics into elementary music education.</span></p>
