摘　　要：热带雨林地区的降雨和蒸发频繁,公路边坡在其交互作用下,土体内发生饱和-非饱和渗流,致使土体的抗剪强度和基质吸力下降,进而影响边坡的安全稳定。本文采用有限元分析软件,结合某热带雨林地区公路,模拟计算了路堑边坡渗流场、安全系数的变化规律,为边坡的开挖和防治提供参考依据。Subject to the interactions of frequent evaporation and rainfall, saturated and non-saturated seepage occurs in highway slope in tropical rain forest, so the shear strength and matric suction of the highway slope will decline, then the stability of the slope is affected.Combined engineering examples, distribution of seepage field and variation of safety factor of slope in tropical rain forest area are analyzed based on finite element software, which provides a reference for prevention and control of slope.

关 键 词：边坡 热带雨林 渗流 安全系数
