爆扩土锚杆稳定深基坑边坡的加固理论及设计施工方法

Theory and Design-Construction Method for Stabilization of Deep Excavation with Blast-Enlarged Soil Anchor

本文介绍采用爆扩土锚杆在垂直深基坑边坡加固中的理论和设计施工方法。这种加固措施,施工方便、设备简单、投资少、承载力高。通过在13m深的垂直基坑边坡加固工程中的应用,并经有限单元法分析,锚杆应力-应变量测和边坡位移监测,证实了这种新的加固方法的可靠性和经济性。

This paper deals with the stabilization measures with 'Blast-Enlarged Soil Anchor' which has been used to stabililze a 13m depth vertical soil slope. Through FEM analysis, measurement of stress-strain of the soil anchor, and monitoring the slope displacement, it has been verified that the new slope stabilization method is of high reliability and feasibility.
