Analysis of Hall Anchor Pulling Force on Soft Soil Condition

Guoyan PENG, Jintai LI, Meng ZHANG, Wenxian TANG, Jian ZHANG


Taking 60kg C Hall anchor as an example. We established the pulling anchor model on soft soil condition based on the theoretical formula and hall anchor simulation model in CEL analysis method of ABAQUS software. That got the pulling force in soft soil and the flow of soft soil. These results show that although the method of theoretical calculation can accurately calculate the pulling force, could not reflect the change of the pulling force with the change of the distance of pulling anchor, and could not assess the stability of the pulling force. In the results of numerical calculation, the pulling force in soft soil is a wave force. In the results of the flow of soft soil, the wave of the force in first 20 seconds is related to the concave pit in the initial formation of the anchor, in this stage, to avoid the slide of the anchor, the pulling speed and the pulling force should be controlled to reduce.
