摘要
本文抛弃了传统土力学中对土块条间推力作用线的方向或其作用点位置的种种假设,对能量原理在条分法中的应用进行了大胆的尝试.提出了用最小位能原理确定条间推力作用线倾角的方法,导出了土块条间推力的计算公式.本方法的运用将使许多斜坡稳定性的评价方法得到改善,使其计算过程更为简单,计算结果更为准确.
Abandoning various assumptions on the directions of interslice forces (or locations of points of action) in conventional soil mechanics, the author boldly tried to apply principle of energy to the slicing way of slope stability analysis. A method for solving inclinations of interslice forces was proposed, according to the principle of least potential energy, in the paper. Formulas for solving interslice forces were deduced. The conventional evaluation method of slope stability will be improved by the application of method proposed in this paper, the calculating process of improved methods will be more simple and results obtained will be more accurate.
