摘　　要：根据管桩的竖向抗压承载力特性和受力状况,通过对预应力敞口管桩与闭口管桩的荷载-沉降试验,结合国内外专家对"土塞效应"的研究,对比分析了敞口管桩与闭口管桩的Q-S曲线形态,研究了两种桩的沉降特性,得出敞口管桩与闭口管桩的不同承载机理及沉降。Accordin with the Q-S g to the hearing capacity character testing of the prestress the plugging effect research by the d alyzes the Q-S curve patterns of the ed Or omest Open tling character of piles of the two types, the Close-end piles shares different bearin en-end ic and f -end an and fin g and s and stress condition of the tubular piles, and Close-end piles, and in association with oreign experts, this paper contrasts and and Close-end piles, and also studies the setally concludes that the Open-end piles and ettlement mechanism.
