摘要
根据土钉现场抗拔试验数据,分析了钉材、浆液龄期等因素对土钉抗拔承载力的影响,建议了合理的下层土钉开挖时间。最后通过试验土钉抗拔力反算土体与锚固体的极限粘结强度,并与规范推荐值进行了比较。
According to the in-situ test data of soil nail, the author analysed the factors that affect the pulling resistance of soil nail, such as soil nail material, serous age and other factors, and suggested a reasonable interval time between upper and lower row nail construction. Finally, the limit cohesion strength between the soil and the nail was obtained by in-situ test, and the results were also compared with those regulated by the technical specification.
