摘要
小直径钢管桩具有施工方便、施工周期短、对岩土体扰动小、造价低等优点,近年在滑坡处治中应用较多。以某高速公路互通区一滑坡的处治为例,介绍了小直径钢管桩处治设计的方案拟定、具体设计及施工过程,并通过施工后的现场监测发现:小直径钢管桩钢管桩变形较小,处治的边坡未出现明显失稳变形迹象。
With the advantages of more convenient,a shorter construction period,a less construction disturbance and low cost,application of small diameter steel pipe pile in landslide treatment is more popular.Takes an ancient landslide in highway overpass bridge for example,the progress of plan and construction are introduced,and the monitoring shows that deformation of these small diameter steel pipe piles is small and the slope is steady.
