Study on the impact of rock and soil properties on pre-stressed cable´s anchoring force loss

Anchoring effect of pre-stressed anchor cable´s mechanism is complicated, the factors that influence pre-stressed anchoring effects are numerous. The anchoring load loss has close relations with rock and soil properties , material character , quality of anchor clamp , construction technology , operate and management level and so on, but the nature of anchored rock and soil properties is one of the most important factor that affect the anchoring effect. Through various means and methods such as geological survey, experimental research, numerical simulation, theoretical analysis, and combined with pre-stressed anchor and other project examples, this paper carries out some Analyses and research on anchoring loss of pre-stressed cable cased by solid rock, weak rock , broken rock and soil body.
