| The driving condition of western district highway net of our country is bad,the highway standard is low and natural disasters such as hill landslide and mud-rock flow etc are very much .There are many difficulties in highway construction and maintaining. The workload and the difficulty of the roadbed protects engineering are more and more great.Anchor-hold technology by the prestress anchor have many advantage. It is convenient and it can forwardly eliminate the press of soil and weaken the distortion the slope effectively, therefore this technique gets extensively use in many projects in domestic and international. This text's research object is a section of a highway on highway landslide. The article structure the landslide prevention and cure , the structure of prestress anchors and its application in detail. Basing on the geology condition of fabricating yard , we calculate the solid power and the length of anchor rope . We have worked out the experiment research scheme , and has carried on the earlier stage experiment, field demarcation experiment and has opened pulling the experiment on the spot.Ten teams of steel rope to two teams of structure types twist the experimental data that thread internal stress and the total pulling force has been in progress research , and has put forward raising the measure of solid capability of prestress anchor and administering possessing . |
