The Technical Impact Analysis Of The Proposed Building Adjacent To The Underground Existing Tunnels

Along with social progress, economic development, people’s living standardsimprove，people travel comfortably and fast requirements also will increase, tunnel as aquick and convenient means of transport, more and more cities fancied, becomes anintegral part of the big transport needs of the city, the security of the tunnel along withit has become a very important issue. In the city’s construction and developmentprocess, existing tunnel in the course of its use, its perimeter will inevitably be avariety of engineering activities, especially in both a large excavation around the tunnel,tunnel surrounding rock’s stress and strain state will change, which affects the use ofthe tunnel safety. In recent years, The proposed construction works on the surroundingenvironment has a lot of research, especially in soft ground excavation，however, in thecase of relatively good rock foundation, The proposed construction on the surroundingenvironment impact study is relatively small, there are still relatively large number ofproblems to be solved.The content and conclusions of this study:According to the current foundation theproposed construction impact on the existing tunnel safety research status, most studiesis the use of finite element software, its analysis of various factors. In this paper, weuse Qingdao Blue Ocean Foundation works as a background, according to existingnorms and theory, analysis during the proposed construction of the existing tunnel mayimpact the stress and deformation of various factors, establish evaluation indexsystem， and corresponding impact assessment of Qingdao Blue Ocean projects;Finally, by numerical simulation software MIDAS/GTS, established analysis model,simulated the proposed construction of the actual construction process, carried out thecorresponding technical analysis, against evaluation system established in this paper tosupplement evaluation. This work will contribute to the technical safety analysis ofsimilar problems, for the corresponding decisions provide some technical support andhelp.
