降雨条件下宾格石笼护坡与浆砌石护坡稳定性比较研究

Comparative Study on the Stability of Binger Gabion Slope Protection and Masonry Slope Protection under Rainfall Conditions

宾格石笼网结构是一种应用广泛的生态护坡方式。对此,以山西省沁源县紫红河干流防护工程为背景,建立有限元模型,分别模拟宾格石笼护坡、浆砌石护坡在降雨工况下的渗流场、位移场、应力场随降雨产生的变化规律。研究表明宾格石笼护坡能够承受较大的外力,制约坡体变形,在限制坡体屈服破坏方面具有更好的效果。结合经济与施工难易程度,建议防护工程采用宾格石笼护坡形式。

The Binger Gabion structure is a widely used ecological slope protection method.In this regard,taking the Zihong River’s main channel protection project in Qinyuan,Shanxi as the background,a finite element model is established to simulate the seepage field,displacement field,and stress field of the Binger Gabion slope protection and masonry slope protection under rainfall conditions.The study shows that the Binger Gabion slope protection can withstand larger external forces and restrict slope deformation,exhibiting better performance in limiting slope yield damage.Considering economic factors and construction difficulty,it is recommended to use Binger Gabion slope protection for the protection project.
