Compaction effect from jacked pile is calculated by finite element method. Compaction effect of soil surrounding pile is taken into account. Modified cam clay model is adopted as constitutive model of soil. A formula of initial tangent modulus of soil with compaction effect is presented. And the model parameters and other calculation parameters are determined by test. Finite element method is applied to calculation for a centrifuge model test and another model test. Computed results show that for analysis of stress and displacement in soil around pile, it is necessary to take plastic characteristics of soil and compaction effect into account.

According to the actual behaviour of the piles wi th branches and pla tes,a model test equipment had been designed to study bearing property and ot her i nfluence factors of the piles with branches and plates. In contrast to the model with e quivalent-diameter pile,it can be seen that the bearing capacity of the pi le with branches and plates is much higher than that of the piles with equivalent-diameter,while its settlement is much lower. The test also proves that the soil unde r the plates make a little contribution to the bearing capacity of the piles.O n th e contrary,there will be negative friction close to the bottom of the plates. Great attention should be paid to this phenomenon. In addition,according to t he laboratory soil test,it is proved that the compaction effect of soil is obvi ously extended through the plates,and it has an active effect to improve the bearing capacity of the piles. A formula to calculate the bearing capacity o f the piles with branches and plates is advanced at last.

根据挤扩支盘桩的实际工作性状,设计了一个室内模型试验装置来研究支盘桩的承载和变形性能以及影响因素,通过与等直径模型桩的对比试验表明支盘桩的承载力远远高于等直径桩,而沉降变形则要小得多。试验还证实盘底土体的侧阻对桩的承载力贡献很小,在紧邻盘底的位置甚至可能产生负摩擦作用,设计时应给予充分重视。另外,根据土工试验表明,通过盘的挤扩作用使其周围土体产生较明显的挤密作用,这种挤密效应对桩的承载力的提高有积极作用。最后提出了一个支盘桩承载力计算公式。
