[摘要]通過在樁身不同部位埋設土壓力盒和鋼筋應力計等原位測試手段,對相同樁長、相同主樁徑的普通直身樁和擠擴多支盤樁進行了對比性試驗,分析了兩種樁在受力機理上的區(qū)別,研究了擠擴多支盤樁的載荷傳遞機理,以及支盤端阻力、樁身側摩阻力隨著沉降、載荷改變的變化規(guī)律,為該樁的進一步推廣提供了理論依據。
[關鍵詞]擠擴多支盤樁;土壓力盒;鋼筋應力計;受力機理

Abstract:A field test is carried out on the mechanism of general pile and muti-plate-pile by means of embedding pressure cells and reinforcement stress gauges. It investigates the distinguishing characters of the special pile, including load transmission law, the variation law of tip resistance and lateral resistance with the change of load and settlement, and so on. Thus it provides new academic information to promote the usage of this special pile.
Keywords:muti-plate-pile; earth pressure cell; reinforcement stress detector; undertake load mechanism
