Shandong Yellow River Alluvial Plain Of PHC Pipe Pile Soil Engineering Characteristics Research

Aging behaviors are frequently observed in many kinds of materials, indicating thegradual changes of certain properties of materials with time elapsing. For ferroelectric materials,the aging behaviors mainly include the phenomena of double hysteresis loops and asymmetryof coercive field.PHC pipe pile, the prestressed high strength concrete pipe pile, is to adopt a prestressedcentrifugal molding process with10atmospheres, around1800℃steam curing and a kind ofthe hollow cylindrical shape Mixed suspected soil prefabricated artifacts is made.PHC pipepile has high bearing capacity, stable quality, strong penetrating power, the construction speedis fast. Construction is convenient, price points, and many other advantages, and therefore it hasbeen widely used.Because of having not specification for PHC pipe pile in shandong province,Due to notvery clear the mechanical properties and load performance of PHC pipe pile, especially aboutthe PHC pipe pile soil compacting effect and liquefaction characteristics, mostly draw lessonsfrom other types of piles, but with the development of the production practice, people graduallyrealize that the PHC pipe pile soil engineering properties and other types of piles differ greatly.So this project is to develop Engineering characteristics of pile soil research of ShandongYellow River alluvial plain of PHC pipe piles.PHC pipe pile has a great influence on the engineering characteristics of pile soil. In orderto find out the engineering characteristics, the project relying on the shandong electric powerengineering consulting institute co., LTD., the existing engineering project, in shandong datanglinqing and binzhou Yellow River alluvial plain are on the power plant project site in situ testand field test in order to study the process of pile sinking piles change law of soil compactioneffect and to evaluate the pile-sinking process on the impact of liquefiable soil liquefaction.And FLAC3d numerical simulation software is used to establish the compaction pile thickliquefied soil layer under the horizontal vibration under the action of dynamic strain model,through the analysis for obtaining the vibration liquefaction development features. Researchresults not only provide the basis for design of PHC pipe piles for power plant project to reduce engineering cost but aiso can be popularization in shandong Yellow River alluvial plain toguide the construction of the whole region.
