Abstract: The bearing capacity experiment of the steel drill anchor was carried out, and the bearing capacity of several typicalsteel drill anchor was researched through the data analysis and curve comparison to provide a reference for all kinds of rescue teams at all levels.The results showed that under the specified setting requirements,the bearing capacity of a single steel drill rod has little relationship with the depth of insertion into the soil. For the single steel drill rod, the insertion of 2/3 and 4/5 had the average bearing capacity of 4.199 kN and 4.564 kN respectively. The bearing capacity of the pickets system is significantly higher than that of a single picket,the average bearing capacity of two pickets system is 8.352 kN, and the average bearing capacity of three pickets system is 10.446 kN. Pickets system, especially the three pickets system, is the better choice if the conditions of actual field rope rescue permit.

Key words: rope rescue, steel drill rod, anchor point, bearing capacity
