摘要
二次高压劈裂注浆能大大提高软弱地层中预应力锚索抗拔承载力。本文在提高锚固力机理方面进行了详细的探讨 ,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。
The second high splitting gruoting can greatly increase the anti-pulling capacity of the cable-anchors in the soft ground,the following paper research discussed the mechanism of increasing the anchorage capacity in details,the formula to compute the anchorage capacity is provided in theory,and also provide a simplified method.It has great directed sense in the designing and construction of the second high splitting grouting cable-anchors.
