摘　　要：不少专家学者在《岩土工程学报》发表过论述边坡稳定性分析中水力概念与计算的文章。对其中的水力概念问题进行了分析,结果表明:动水压力一词可以按其本意使用;《建筑边坡工程技术规范》(GB 50330—2013)条块底面总水压力计算公式采用了符合原意的动水压力算法;渗透力和浮力是周边水压力的组合力,对这二力的认识应建立在这个基础上。Many experts and scholars have published papers on the concept and calculation of hydroenergy in slope stability analysis in Chinese Journal of Geotechnical Engineering,analyzing the concept of hydroenergy.The results showed that the term“hydrodynamic pressure”can be used as its original meaning;Technical Code for Building Slope Engineering(GB 50330-2013)gives a computational formula for the total hydraulic pressure on the fragmented bottom based on the one for hydrodynamic pressure consistent with the original meaning;seepage force and buoyancy are the combined forces of the surrounding hydraulic pressure,which is the basis for the understanding of the two forces.
