| With the continuous development of urban construction,the springing up of the high-rise buildings and the opening up of the underground space,The foundation excavation project is increasing greatly.The soil anchor bolting technique more and more applications in deep foundation pit slope support.How to resolve the deep foundation pit slope support problem safety and economically is a rock soil-engineering topic that has been the biggest realistic meaning.At the same time,soil anchor became widely use attribute to the rapid construction of project the light and cheap of equipmentã€the simple of technique and the cheap of construction. But as a result of anchor working conditions complexity and not determinism, it effecting mechanism about the anchor is unsure.Considering the the particularity of the anchor, we consider the model experiments is the most effective research techniques. During the study of anchor carries on positively, investigating the reason why anchor is failure and analysis the measure how prevent the disease of anchor could supplement the research of the anchor.Combination of theory and practical are used in this paper, in the direction of the soil anchorth stress distribution are test.Firstly, the article study the anchormechanism theory of existent Anchor mechanism theory and some of methods of how caculated the inner-force of anchor,which emphasize on researching the anchoring mechanism and calculating of inner-force.Then,the common diseases are summarized and a preliminary analysis.Through tension type anchor model test in the context of different length,distribution of the sheer stress and the axial force are given by the anchor rod.Finally,we have got the stress of anchor bolt by the test and theoretical calculation.Disasters of the anchoring construction are analyzed.And corresponding prevention and treatment measures are put forward.Combining with theoretical calculations, the stress distribution of soil anchor have been studied in this paper. The paper analysis the typical distress and damaged mechanism of soil anchor and puts forward the preventive measures.anchorage technology has been considered as an important theoretical basis in many areas such as slope, the foundation engineering, the design of anchoring engineering, the analysis of construction technology. |
