本文提出一种确定粘性土地震土压力及其合力作用点位置的新方法,按破裂面为平面的假定,导出了一般性电算公式,文中通过算例,对新平面法和现有较好的平面法进行了比较,并分析了多种因素的影响,文末给出了初步结论。 由于公式首次吸取了动力研究的合理结论,提高(或降低)了主动(或被动)土压合力的作用点位置,使其主动压强分布图与有限元分析的结果较为接近,这样既改进了静力假定,又比现有平面法安全。公式的物理概念清晰,便于考虑多种因素的影响。
This paper presents a new method to determine the seismic earth pressures of cohesive soils and the positions of their resultant forces. Based on the assumption that the rupture planes are planes, a general formula for electrical calculations is derived. In this paper, a new example and a better method for the new plane method are obtained. The plane method was compared, and the influence of various factors was analyzed. Preliminary conclusions were given at the end of the paper. As the formula for the first time draws a reasonable conclusion from the dynamic study, the position of the active (or passive) soil pressure force is increased (or reduced), and the active pressure distribution map is closer to the result of the finite element analysis. This not only improves the static The force is assumed to be safer than the existing planar method. The physical concept of the formula is clear and it is easy to consider the influence of many factors.
