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.

Increasing performance of steelmaking units is possible with  changing methods of steel production. Such variances entail serio us  changes in the subsequent redistributions: in metals processing by  pressure and in thermal treatment of finished metal products. It is  known that these two metallurgical processes are equipped with a  large number of heating and thermal furnaces, and their thermal work  does not always meet increased requirements for products quali ty.  Issues of improving thermal performance of furnaces are also relevant in mechanical engineering. High technological requirements  are associa ted with very strict environmental ones. Therefore, a new  concept is needed for the design and construction of modern highly  automated industrial heating furnaces. In order to improve the design  and technical and economic indicators, technical obsolescence and  the construction of new industrial furnaces are carried out. In design  and construction of furnaces, fuel-burning devices of new designs  and modern materials are used. In turn, this necessitates the use of  new approaches to working space and heating system design of the  furnace, taking into account arrangement of heated products charge.  Such events are carried out, as a rule, in operating workshops, that  causes certain difficulties due to limited space provided for placement of new furnaces and equipment for their operation and maintenance. A complex study was made of the design and thermal performance of a block of three chamber thermal furnaces. They were built  in a limited space of the workshop with specific loading and delivery  of heated thin sheet.
