The mechanism of the anchorage effect of the anchorage cable is very complicated. There are many factors which affect the anchoring effect. The loss of anchorage force concerns with the qualities of rock and soil masses, materials, anchor clamping, the construction technology and operation and management level and so on. Taking the Pre-stressed anchorage projects as examples, with the method of geological survey, experimental study, numerical simulation, theoretical analysis, the paper makes study on the loss of anchorage force caused by the qualities of hard rock, weak rock, and broken rock and soil masses. This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text.
