Research on the Anchor of Inside-Soil-Opened Umbrella Type & Its Jacking Force
Abstract:
The existing soil anchor of steel strand encapsulated by cement has many disadvantages such as longer anchorage length, more construction process and not timely bearing load. Contrary to the existing soil anchor, the anchor of inside-soil-opened umbrella type has lots of advantages: simple structure, convenient construction, high bearing capacity, timely anchoring soil. This paper has analyzed the principle of anchorage and jacking force of the soil anchor, also given the estimated equation of the jacking force. The result of experiment shows that the change of the dragging force is not obvious with the increase of the jacking distance, and the frictional force performs linearly with the increase of the jacking distance. So the estimated value of the jacking force anatomizes the practical value.
