摘要
2017年7月,受强降雨影响,赤水市石堡乡牛路口山体斜坡区发生开裂变形,并持续发展形成滑坡,在结合地面调查及钻探勘查的基础上得出结论,该滑坡为已推移式滑坡,滑坡土层较厚,最厚可达20m,土体渗透性极弱。通过常规反演及有限元模拟计算最终提出挡土墙+抗滑桩+地下排水+地面排水的综合治理方案。
Affected by heavy rainfall in July 2017, the slope at Niulukou of Shibao town of Chishui city cracked and deformed, and then developed into landslide. Combining surface investigation and drilling survey, it was concluded that this landslide evolved intoa traction type. The soil layer of the landslide is thick to reach 20 cm, and the permeability of the soil mass is extremely poor. By conventional inverting and finite element modelling and calculation, the comprehensive treatment scheme, consisting of retaining wall, slide-resistant pile, underground drainage and surface drainage, was put forward.
