摘要
对圆形基础作用下纯粘无重土的塑性流动，给出了基本满足静力许可条件的应力场和完全满足运动许可条件的速度场．运用虚功率原理，求解出该基础的极限承载力解析解，它较数值积分计算简明、精度较高、结果较理想，可供工程设计参考．
In relation to the plastic flow of purely cohesive null gravity soil under the action of a circular foundation, the author assumes a stress field which satisfies basically allowable equilibrium and a velocity field which satisfies completely allowable motion; and solves the analytical solution of ultimate bearing capacity of that foundation by applying the principle of virtual power. This is a concise method with result in higher accuracy, as compared with that of numerical integration computation. It may serve as a reference to engineering design.
