| Abstract: | In this paper, the influential factors of anchorage in loess and the construction technology increasing anchoring force are discussed on the basis of in situ anti pulling tests. In addition, the distribution of stress around cable anchorage system in loess is analysed by using finite element method. Then, the anti pulling force and design parameters are suggested, which provides the basis for engineering design. |
