摘　　要：在水泥土挡墙抗倾覆稳定性计算中,墙面水压力和墙底水压力的定位有过三种不同方法,即:(1)前者为抗力,后者为作用;(2)前者为抗力,后者为负的抗力;(3)前者为负的作用,后者为负的抗力。有的学者对危岩抗倾覆稳定性计算中不同方向水压力的定位也建议采用第三种方法。分析表明,这些方法都违背了水力学基本规律。为此提出了水泥土挡墙和危岩不同方向水压力定位的不同主张。In the calculation of the anti-overturning stability of cement-soil retaining walls,there are three different methods to locate the water pressure on the wall surface and the water pressure on the bottom of the wall.That is:(1)resistance and effect;(2)resistance and negative resistance;(3)negative effect and negative resistance.Some scholars also suggest the third method for the positioning of water pressure in different directions in the calculation of the anti-over-turning stability of dangerous rocks.Analysis shows that these methods violate the basic laws of hydraulics.To this end,different proposals were made for the positioning of water pressure in different directions for cement-soil retaining walls and dangerous rocks.
