Behavior Analysis Of Anchored Pile Of Reinforce Cement Soil With The Shape Of "∏"

Anchored pile of reinforce cement soil with the shape of "Π" is one kind of building foundation supports and protections emerging technology in recent years, which is more superior than the traditional supports and protections technology in safety, economy and convenience of construction and so on . At present it obtained already more and more applications in the actual project. But there has no design calculation theory research analysis about this kind of new supports and protections structure until now, thus it caused that the design construction only to occupy imitates in others experience's low level. Therefore, as to three aspects character of this supports and protections structure system—the internal force, deformation and stability, this article launches more thorough research by means of the theoretical analysis and the numerical simulation, and proposed a kind of practical computational method based on the elastic resisting force method. The main task is introduced as follows:1. Through the theoretical analysis of mechanics and the structure effect for this supports and protections structure, proposed computation model based on elastic foundation beam theory, and derived solution formula to the analytic solution of the internal force, deformation about the supports and protections structure;2. Embarked from the existence question of the present stable checking calculation method, established analyses model and the checking calculation method about the stability of this supports and protections structure using the limiting equilibrium principle, and analyzed the influence extent of the primary structure parameter on stability;3. Carried on the brief trussing finite element analysis to this supports and protections structure, and carried on the computation using the theoretical calculation method to the project example;4. Through the FLAC numerical simulation analysis to the project example, and the contrast with the theoretical calculation result, the rationality of the theoretical analysis computation is further confirmed. Then the contrastive analysis is carried on using the horizontal displacement value as the evaluating indicator of this supports and protections structure's main design variable, and its character rule is summarized.The research results indicated that the Anchored pile of reinforce cement soil with the shape of "Π" supports and protections technology has the good capability of the deformation control and the overall stability. This research work of this article has the very good reference value to establish the design calculation theory to this supports and protections structure.
