Design And Application Of Pile - Anchor Retaining Structure For Deep Foundation

With the accelerating pace of domestic construction,in order to adapt to the needs of engineering construction,pile anchor retaining structure began to be applied in engineering and developed step by step during the 1980 s. Because pile anchor retaining structure has the advantages of low cost,easy construction,low technical requirements and environment effect,it has been widely used in the governance and regulation of the landslide of the deep foundation pit at present,and is one of the most basic forms of support in the deep foundation pit supporting project. The study on pile anchor supporting structure is mainly focused on the theoretical calculation,construction technology and application.In this paper,combined with the engineering practice design theory and method of deep foundation pile anchor retaining structure were analyzed and studied from the basic theory of existing. Combined with the features of deep foundation pit engineering and pile anchor retaining structure, application and the development of the status quo of the pile anchor retaining structure are summarized in deep foundation pit engineering. Through the summary and analysis of the calculation method of earth pressure to deep foundation pile anchor retaining structure, the applicable conditions of various theoretical calculations are summarized. Aiming at the pile anchor retaining structure calculation theory and method, the applicable conditions, advantages and disadvantages of the various theories and methods are compared and summarized. The design method of pile anchor supporting structure is researched, the supporting structure and the stability of the bolt is checked. Combined with the engineering example, pile anchor retaining structure of deep foundation pit is calculated and analyzed by different methods, and the advantages and disadvantages of different calculation methods are discussed. The calculation and analysis of the design method of the pile anchor retaining structure in deep foundation pit is summarized.The Suggestions of the design of pile anchor retaining structure in deep foundation pit in the calculation were put forward.
