Urban underground engineering construction may have bad influence on the environment and even cause disasters. Pipe-roof Pre-construction Method(PPM) had been used in building a metro station of line No.2 of Shenyang subway. It's very important to analyze and evaluate the deformation of the environment in order to ensure the safety of constructing procedure. So, based on the detailed study of geological...
Based on the large-span spatial structure of Ordos's airport terminal, an impermanent supporting system arrangement scheme was put forward during the construction of a large-span spatial steel structure. By FEM analysis, the member force and deformation of the supporting system in construction were got and its availability was validated. Therefore, a whole removal scheme of the supporting system was...
Task conditioning aims to provide each occupant with personalized clean air direct to the breathing zone. Microenvironment of a typical office workplace consisting of different task air conditioning system, such as CMP (computer monitor panel), MP (movable panel), horizontal desk grill (HDG) and vertical desk grill (VDG) are studied by numerical simulation. Numerical simulation by k-epsiv 3-D turbulent...
Safety construction of deep foundation pit in narrow space is one technology difficulty. Analysis on the deformation of adjacent building during excavation and supporting is the key factor. Taking the deep foundation pit, supporting structure and surrounding buildings as one system, this paper applies the numerical simulation analysis method to carry out the comparative simulation for the changing...
