摘要：In hydraulic engineering, sometimes it is necessary to consider the stability of sliding bodies with lateral frictional boundaries. Neither the existing three dimensional limit equilibrium methods nor the commercial software products are able to treat such situations. The three dimensional factor of safety is accordingly underestimated; while the shearing strength based on the three dimensional back analysis is overestimated. In this study, the lateral boundaries are regarded as the part of the slip surface. Based on the expression of the normal pressure on the slip surface and the patch interpolation, a rigorous solution for the three dimensional limit equilibrium analysis is realized. Meanwhile, the proposed procedure is applied to the stability analysis of the slope with a cable platform on the right bank in Da Gang Shan hydraulic project under construction.

摘要：This paper aims, first of all, to examine the two fundamental treatments of the complex and very broad notion of chrematistikd （money-making） and its links with the notion of oikonomia （economics）, outlining a fundamental division between natural and unnatural art of money-making. The two different arts of money-making are based on two very different psychological attitudes： in the first case, desire is channeled, managed, and organized by practical wisdom with a view to a further end; in the second case, desire is an end unto itself, insatiable, boundless and contrary to the commands of practical wisdom. Only in the first case there is a ＂true wealth＂, that is a wealth oriented toward a good life that constitutes the end （telos） and the limit （peras） of the wealth itself. The conclusion is that, for the Stagirite, wealth is not an evil, nor, in itself, is the pursuit of wealth, that is, the art of money-making, because if it is rightly organized and oriented in function of the end, it constitutes the conditio sine qua non of a life that is good, ordered and happy for the individual and for the city
