АНАЛИЗ ВЛИЯНИЯ ЛИВНЕВЫХ ОСАДКОВ НА УСТОЙЧИВОСТЬ СКЛОНОВ Stability analysis of soil slopes subject to action of rainfall-induced wetting front

Xiangzhou Mao, Bin Zhang, Wenxi Fu


Приводятся результаты исследований устойчивости однородных пологих склонов, для которых триггером потери устойчивости являются интенсивные (ливневые) осадки. Приведен расчет коэффициента запаса устойчивости оползневого тела, состоящего из трех фрагментов (центрального и двух краевых). Рассматривается зона поверхностного водонасыщения, а также
возможность поверхностного потока при интенсивности дождя, превышающей водопоглощение грунта. Показано, что коэффициент запаса устойчивости склона уменьшается с увеличением водонасыщения и ростом глубины поверхностного водного потока. Экспериментальные результаты хорошо согласуются с теоретическими.
