Study On The Anti-overturning Bearing Capacity Of Concrete Extended-plate Pile Under Horizontal Force

In the field of basic engineering,there is such a new type of pile-the concrete extended-plate pile.It is improved on the basis of ordinary pile type.Using the process of spin-expanding.extrusion,etc.The bearing capacity expansion disk is added to the original straight-hole pile.The overall bearing capacity of the pile body is changed?the frictional resistance of the pile side and the bearing capacity of the pile end are improved,and its development prospect is large,and the advantage is unique.At this stage,under the vertical load.the concrete expansion pile has achieved remarkable results.But the research on the horizontal load is still in the preliminary stage.In order to improve the results of horizontal force research,this paper uses model test and ANSYS simulation analysis method are used to study the influence of rigid and flexible piles on the overturning bearing capacity of concrete expanded piles under horizontal force.In the test,an innovative small-scale half-face pile undisturbed soil model test method was used,and the earth borrower and loading test device were specially prepared.Design and presentation of half-face piles,can clearly see the various stages of the interaction between pile and soil.and integrate the top displacement value with the corresponding horizontal load.System analysis of model test results.Simulation analysis of rigid and flexible concrete expanded piles by using ANSYS software to collect corresponding displacement,load,stress and strain data,Furthermore,the failure state of the surrounding soil of rigid and flexible piles is analyzed,and the change of anti-overturning bearing capacity is analyzed.Because the disk position is the main factor affecting the ability to resist overturning,this paper studies the damage state of rigid and flexible piles at different disk positions under horizontal loads.Research shows that in the test,an innovative small-scale half-face pile undisturbed soil model test method was used,and the earth borrower and loading test device were specially prepared.Design and presentation of half-face piles,can clearly see the various stages of the interaction between pile and soil.and integrate the top displacement value with the corresponding horizontal load.System analysis of model test results.Simulation analysis of rigid and flexible concrete expanded piles by using ANSYS software to collect corresponding displacement,load,stress and strain data,Furthermore,the failure state of the surrounding soil of rigid and flexible piles is analyzed,and the change of anti-overturning bearing capacity is analyzed.Under the vertical load,the concrete expansion pile has achieved remarkable results.But the research on the horizontal load is still in the preliminary stage.In order to improve the results of horizontal force research,this paper uses model test and ANSYS simulation analysis method are used to study the influence of rigid and flexible piles on the overturning bearing capacity of concrete expanded piles under horizontal force.
