| The main purpose of this essay is to complete the support design of deep foundation pit slope engineering, solve the technical problems from the process of engineering design, as well as discuss the design procedure and construction application of construction technology of the pile anchor support system of deep foundation pit. The deep foundation pit of HeLong&City Living Ground has been taken as example in this essay, with help of technical knowledge learned from campus and construction methods from internship, referring some current design specifications, construction specifications, reports and design materials of relative topics. The detailed design of this engineering example and procedure explanation of construction points have been completed, and the following contents have been mainly researched in this essay:1.With the stability analysis through limit equilibrium method, the deep foundation pit slope from HeLong&City Live Ground has been vertically excavated, which determines its depth of excavation and potential slip surface.2.The general methods of deep foundation pit support design have been researched, from five aspects, including case design, structural analysis, members design, stability verification and drawing working plan, to conduct induction and arrangement of design procedure.3. Referring the HeLong&City Live Ground, the current specification and design points have been researched, as well as completing the detailed supporting structural design and stability verification of deep foundation pit slope from AB part of this engineering.4.The AB part of deep foundation pit slope in HeLong&City Live Ground has been supported with pile anchor, with construction arrangement and explaining the procedure of test points.5. The general design and working of construction have been concluded, with discussing the potential-improving points and the further work in the future. |
