深水桥梁基础施工时的钢护筒在钻孔灌注桩施工完毕后保留，桩体实际上形成了上大下小的变截面混合桩。利用钢护筒参与桩身受力来改善基础的抗震性能，具有高效、简便且又经济的突出特点，有广泛的应用前景。本文针对目前钢护筒混凝土灌注桩的应用、研究现状、钢护筒混凝土桩和钢管混凝土桩的区别以及钢护筒混凝土灌注桩的基础抗震性能研究存在的问题等进行了总结与归纳，并提出一些建议。为钢护筒混凝土灌注桩的进一步研究提供参考。

The steel casing was left after the construction of cast-in place piles when constructing the deep-water bridge foundation.Then the pile actually formed a variable section pile which has a bigger section area at upper part and a less area at down part.To use the steel tube for force can improve the seismic performance of pile foundation,which has the advantages of high efficiency, simple and economi-cal and has wide application prospect.Accorsing to the current situation of research and the application of steel tube concrete drilled pile, the difference between steel tube concrete pile and steel pipe concrete pile,the problem in the research of basic seismic performance of steel tube concrete pile, the paper point-ed out some suggestion which can provide a reference for the further research of steel tube concrete pile.
