The main purpose of this paper is to analyze the stability and safety problems of braced excavation enclosure, surrounding strata and side slope during construction of Shangshuijing station in Shenzhen Metro Line 5. The paper presents stability discrimination of the braced excavation and side slope by discussing their force and deformation regularity using Flac3D, and puts forward some project proposals about its design and construction. The results show that: (1) The stability coefficient of braced excavation enclosure becomes smaller because of biasing impact of side slope, but this project can meet the stability requirements, (2) The biasing impact of side slope has little influence on deformation of surrounding strata starting on the other side of braced excavation without slope, and (3) To ensure construction safety under condition of side slope, the braced excavation should be excavated starting from the zone far from the side slope, steel pipe can be used as assistant reinforcement at the corner of side slope if necessary.

Taking into consideration the complexity of the new, heterogeneous, and different training needs currently present in the classrooms, the school is called to respond them in an effective and concrete way through inclusive educational approaches centered on the students, none excluded. On this basis, the authors, supporting the importance of technology in innovative teaching, propose the design and construction of an intelligent white stick through an inclusive cooperative methodology. The presented device, presented in this paper, is inspired by an open and collaborative teaching, enhancing a responsible digital education, accepting the training needs of all the students present in the classroom, specifically the blind student, and the recognition of the diversity in view of the reduction of disability.
