摘要
在基坑支护工程中,土钉墙支护是较为常用的支护方式,土钉一般选用钢筋作为杆体筋材,但钢筋土钉易遭受腐蚀而失效;另一方面,埋置于土层中的钢筋土钉在后期坑道工程开槽施工中形成了障碍,增加了施工难度和处理费用,也不利于节约资源。通过将全螺纹纤维增强树脂杆体作为土钉主筋在基坑支护工程实践中的试验与应用,总结了全螺纹纤维增强树脂杆体土钉用于基坑支护工程的可行性。
In foundation excavation support engineering, soil-nailing wall is a common method and steel bars are generally used which often lead to failure. On the other hand, steel bars for soil nailing in tunnel engineering often become obstacles, increase the difficulty of construction and costs. Based on engineering practice and test, this paper summaries the feasibility of thread fiber reinforced resin bolt support engineering of soil nailing used in foundation excavation.
