针对土钉加固的多地层边坡,提出了一种基于最小势能原理,通过分析系统势能与虚位移来计算边坡安全系数的稳定性分析方法。通过与极限平衡法结果进行对比,并对结果进行讨论,验证了所提方法的合理性。计算结果表明,该方法与Bishop法、Janbu法的分析结果较为一致。该方法无需划分条块及迭代,计算过程相对于极限平衡法与有限元法来说更为简便,便于在岩土工程中推广应用。
Aiming at the multi-layered slope reinforced by soil nailing, a stability analysis method based on the principle of minimum potential energy to calculate the slope safety factor by analyzing the system potential energy and virtual displacement is proposed. By comparing with the results of limit equilibrium method and discussing the results, the rationality of the proposed method is verified. The calculation results show that the method is in good agreement with the Bishop method and the Janbu method. The method does not need to be divided into blocks and iterations. Compared with the limit equilibrium method and finite element method, the calculation process is more simple and convenient for application in geotechnical engineering.
