梧州市滑坡治理工程桩锚支护设计优化探讨

Study on Optimum Design of Anti-slide Pile and Anchor Support for Landslide Treatment in Wuzhou

文章结合梧州市的地层特性,将市区内分成花岗岩地区和砂岩地区,建立两个理想滑坡岩土计算模型,通过模型尺寸的变化,各计算了9个滑坡推力,针对每个模型及滑坡推力使用计算机设计软件进行了4组抗滑桩或抗滑桩锚索组合结构设计计算,并估算出相应各组合的工程造价,在保证安全和施工方便的前提下提出了抗滑桩锚索组合设计优化建议,为滑坡治理工程中抗滑桩与锚索匹配选择的优化设计提供指导依据。

Based on the formation characteristics of geological layer of Wuzhou whose urban area is divided into areas of granite and sandstone,two ideal landslide geotechnical models are set up in this article.It calculates 9 landslide thrusts by varying model size,makes design calculation on 4 groups of anti-slide pile or composite structure of anti-slide pile and anchor through computer design software for each model and landslide thrust,and estimates the engineering cost of each group.It provides suggestions for optimizing the composite structure of anti-slide pile and anchor for the safety and convenience of construction,which is helpful for landslide control project.
