Aiming at analyzing the mechanism of slope failure and evolution propagation induced by typhoon and rainstorm, a numerical simulation of the safety state of a slope was carried out based on the measured rainfall data during various typhoons in Fujian Province of China. For the slope before instability, Monte Carlo method was used to calculate the real-time failure probability and reliability index and reveal the transient change characteristics of the seepage field and plastic zone of the slope. For the slope after instability, Herschel-Bulkley-Papanastasiou (HBP) model was used to describe the rheological characteristics of the slope using the SPH method. The propagation process of landslides was analyzed in terms of velocity and accumulation characteristics. The results show that the rainfall is the key factor to induce slope instability. When the slope failure occurs, the sliding speed of the leading edge can reach 15 m/s. This study provides a reference for the early warning and disaster prevention and mitigation of slope engineering under extreme conditions.

为分析台风暴雨诱发边坡破坏机理,基于4个台风期间实测降雨资料,针对福建某边坡遭遇台风暴雨时的安全状态开展数值模拟,以分析台风暴雨诱发边坡破坏及演进传播机制。对于失稳前的边坡,基于有限元法采用蒙特卡罗法计算边坡实时失效概率、可靠性指数,并揭示边坡渗流场及塑性区的瞬时变化特征。对于失稳后的边坡,基于光滑粒子流体动力学方法,采用基于Drucker-Prager准则的Herschel-Bulkley-Papanastasiou(HBP)流变模型计算其失稳后大变形行为,进而从滑动速度和堆积特征等方面分析滑坡动力灾变过程。结果表明,降雨是诱发边坡失稳的关键因素,边坡发生失稳后,其前缘滑动速度可达到15 m/s。研究结果可为极端条件下边坡工程的安全预警和防灾减灾提供借鉴。

为分析台风暴雨诱发边坡破坏机理,基于4个台风期间实测降雨资料,针对福建某边坡遭遇台风暴雨时的安全状态开展数值模拟,以分析台风暴雨诱发边坡破坏及演进传播机制。对于失稳前的边坡,基于有限元法采用蒙特卡罗法计算边坡实时失效概率、可靠性指数,并揭示边坡渗流场及塑性区的瞬时变化特征。对于失稳后的边坡,基于光滑粒子流体动力学方法,采用基于Drucker-Prager准则的Herschel-Bulkley-Papanastasiou(HBP)流变模型计算其失稳后大变形行为,进而从滑动速度和堆积特征等方面分析滑坡动力灾变过程。结果表明,降雨是诱发边坡失稳的关键因素,边坡发生失稳后,其前缘滑动速度可达到15 m/s。研究结果可为极端条件下边坡工程的安全预警和防灾减灾提供借鉴。

Aiming at analyzing the mechanism of slope failure and evolution propagation induced by typhoon and rainstorm, a numerical simulation of the safety state of a slope was carried out based on the measured rainfall data during various typhoons in Fujian Province of China. For the slope before instability, Monte Carlo method was used to calculate the real-time failure probability and reliability index and reveal the transient change characteristics of the seepage field and plastic zone of the slope. For the slope after instability, Herschel-Bulkley-Papanastasiou (HBP) model was used to describe the rheological characteristics of the slope using the SPH method. The propagation process of landslides was analyzed in terms of velocity and accumulation characteristics. The results show that the rainfall is the key factor to induce slope instability. When the slope failure occurs, the sliding speed of the leading edge can reach 15 m/s. This study provides a reference for the early warning and disaster prevention and mitigation of slope engineering under extreme conditions.
