摘要
土钉支护结构由于其诸多优点在深基坑中得到广泛应用,但是土钉长度布置问题一直是一个热点问题。本文研究了土钉长度的布置方式,结合工程实践,基于内部整体稳定性安全系数最小值的限制原则分析了土钉钻孔直径、水平倾角以及土钉间距等设计参数对土钉长度的影响,最后分析了不同土钉长度布置方式对安全系数的影响,所得结论可供工程技术人员参考。
The soil nailed wall is applied widely in deep excavation for its many advantages, but the layout issue about soil-nailed lengths is always a hot topic. In this paper, the layout of soil-nailed lengths is discussed. In combination with the engineering practice, the influence of the design parameters such as boring hole diameter, inclination angle and spacing of soil nails on the soil-nailed lengths is studied based on the principle of the limited minimum safety factor of the internal overall stability. Finally, the influence of different layout of soilnailed lengths on the safety factor of stability of the soil nailed wall is studied. The conclusions obtained can provide some references for the engineering technicians.
