摘要
二次劈裂注浆能大大提高软弱地层中预应力锚索抗拔承载力。对提高锚固力机理进行了详细的探讨,在理论上提出了计算锚固力的公式,也提出了简化的计算方法。这对二次劈裂注浆锚索的设计与施工具有较大的指导意义。
The secondary splitting grouting can greatly increase the anti-pulling capacity of anchor cables in the soft ground stratum. The mechanism of the increasing of the anchorage capacity is discussed in detail. The theoretical formulas of the anchorage capacity and a simplified calculation method are provided. The results are significant to the design and construction of anchor cables with secondary splitting grouting.
