| 摘 要： | 14号台风“云娜”造成我国东部沿海地区发生多处滑坡地质灾害，张溪滑坡便是其中个案。通过对张溪滑坡成因进行分析，得出了张溪滑坡是在一定厚度覆盖层、特定地形条件、植被条件下，台风风力加载作用及暴雨的淘蚀、软化、增重等一系列过程共同作用下滑动失稳的滑坡。它与暴雨型滑坡的形成机理有显著不同，这一分析成果对类似滑坡的研究和防治具有一定的意义。

| Abstract: | Typhoon,NO.14,named "Yunna" caused many landslides in the east inshore area of our country.The landslide in Zhangxi is one case of all.By deformation cause analysis of that Landslide,we can come to the fact that Zhangxi landslide occur are not only because a definite depth of Q_4 lay,suitable terrain,vegetation etc.,but also especially because wind force push the tree and soil,heave rain made the soil more weight,shear zone soften etc..Typhoon's Wind push the trees and soil mass on the slope accelerate the slope sliding which is the very characteristic of Zhangxi landslide.It would be very different from the landslide caused only by rain.This will be helpful for landslide study and its prevention. |
