摘要
本文主要介绍某地下车库基坑土钉支护设计与施工。该工程在填土层采用钢花管锚杆取代钢筋锚杆解决了填土中成孔困难、施工难度大的问题,保证了施工进度,并根据场地条件,在支护设计时适当提高填土层抗剪指标,为业主节省大量投资。
This paper mainly introduces design and construction of soil nailing support for foundation pit of a certain underground garage. Anchor bars were replaced by steel perforated pipe bolt to overcome the difficulty of pore-forming and construction, ensuring construction progress as well as saving a lot of investment by the adjustment of shear strength index of fill stratum based on the site conditions.
