| Abstract: | 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. |

| Keywords: | cable-anchors the second high splitting grouting the spreading radius of the grout the anti-pulling capacity |
