Stress Research And Connection Methods On Oblique-inserted Slab-pile Wall Anchoring Slab

At present,the oblique-inserted slab-pile wall is a new type of slab-pile wall supporting structure,which offers greater economical and environmental efficiency.It not only improves integrated construction,efficiency and future developments but also future research.Although,at this stage the connection type of oblique-inserted slab-pile anchoring and hanging methods is still an emerging technology and does require further research:Anchoring methods and the viability of locations still requires additional testing.In addition,stress research and testing needs further consideration.Especially,in relation to soil pressure calculations of this type of structure lack theoretical calculation formulae and distribution patterns which require further proof.Firstly,the article summarized four frequently used methods of positioning technology of steel bars their deficiencies and how they can be improved.Based on accepted positioning methods of anchoring steel bars,it's able to avoid the conflict between main reinforcements and stirrups.This method of positioning technology of steel bars is developed to be appropriate for the oblique-inserted slab-pile wall of anchoring slabs,can be applied to the engineering practice,and is highly effective.Secondly,using indoor tests of five different anchoring slabs,being 250mm?300mm?350mm?400mm?450mm.The scale of the model geometric dimension and similarity relation is 1:20 of geometric dimension of BiJi ShanYi Business Center——ChaMa HuaJie supporting engineering.Then,after indoor model tests were performed numerical simulations using ABAQUS finite element software.Through these tests and simulations,results drew the stress-depth curves,pressure-depth curves and stress-length curves through analyzing the data to ascertain the distribution regularities.Lastly,deducing theoretical calculation formula of soil pressure behind the oblique-inserted slab-pile wall of anchoring slab,and combined and analyzed the tests data and simulation results to get a theoretical calculation formula method of soil pressure apply to the oblique-inserted slab-pile wall.
