摘要
从两类特殊渗流条件下的孔隙水压力入手,应用有效应力原理和Lagrange插值方法建立了无限斜坡稳定性分析安全系数的统一形式,从而形成了完整的无限斜坡稳定性分析方法,通过工程实例对所建立的统一形式进行了验证。该文提出的在渗流影响下无限斜坡稳定性分析对类似滑坡分析有一定的借鉴作用,尤其对于复杂渗流条件下的流场研究程度较高的重要道路工程地段及桥涵附近边坡稳定性分析、坝基抗滑稳定性分析与验算等问题的研究具有实践指导意义。
Based on pore water pressure of two kinds of special seepage conditions for infinite slope, unified safety factor formula has been established by applying effective stress principle and Lagrange interpolation method. Accordingly, integrated stability analysis method of infinite slope have been formed and unified formula established have been verified by engineering examples. Stability analysis method mentioned above may be taken as the reference for landslide with similar conditions especially important road engineering, slope nearby bridge with complicated seepage conditions and clear seepage flow net. It is also a practical guideline for stability analysis and checking calcuation against sliding for dam foundation.
