Infrastructure construction is located in Xi39。an city the Chinese people39。s Liberation Army The Fourth Military Medical University. Based on the environment, surrounding foundation pit formation condition, hydrogeological condition analysis, according to the relevant standards and procedures, to the foundation pit excavation and support scheme to the demonstration, calculation and optimization. In order to ensure that the supporting feasibility and economy. The main content of this design: supporting scheme selection, calculation of pileanchor retaining structure design, the integral stability analysis of foundation pit excavation, checking against heave stability, design of foundation pit dewatering, foundation pit monitoring and construction. Pileanchor retaining structure design includes the design of slope protection pile design and anchor cable, anchor design specific row number, spacing, length, steel grade and strength of anchor cable, the design of the slope pile including diameter, reinforcement, pile length, depth calculation, concrete grade. By using the calculation method of layered excavation and the equivalent beam method. The overall stability analysis using a simple Sweden slice method. Checking dewatering design including precipitation method selection, construction, foundation pit dewatering well. In addition a brief design and construction of foundation pit monitoring. Key words: deep foundation pile anchor foundation pit stability 華北水利水電大學(xué)畢業(yè)設(shè)計(jì)(論文) 目 錄 摘 要 .......................................................................................................
