Anchorage Of Reinforced Cement-soil Deformation Of Soil Bound By The Role Of Analysis And Application

Anchored pile of reinforce cement soil with the shape of"door"is a new technology in pit shield, and it is better than the traditional method in safety,economy and convinence of the execution. But, it is obvioursly that the study on this new techonology can't meet the requirements of the practice, due to the the theory gets behind the practice, this is ubiquitous phenomena in geotechnical filed. Up to the present, there is no sysremic theory on design and analysis for this type of shield, that result in the calculational model get adrift to the factual forces and deformation and actual theory has little significance of guidance for practice of engineering because copying the patern of design for traditional system of shield and overlooking the features of its own. So it is imminence to carry out investigation on the theory for design to meet the requirements of the practice in engineering. Hereby, the subject of this paper has crucial value for analysis of deformation,internal force and stability of the anchored pile of reinforce cement soil with the shape of"door"in practice.In allusion to the characters of the anchored pile of reinforce cement soil with the shape of"door", the thesis establishs model of analysis based on the soil-pile interaction, and put forward method of calculation based on ealatic and finite element respectively. And the established model is prowed to be reasonable and credible by applying it to a case study. The mechanism of the deformation of this system of shield has been brought forward and elements that has influence on the deformation has been analysized in detail.The extent of the enhancement in ability of resistence to bending has been elicited by analysizing its internal force. And the caculational method of the stability and deformation has been put forward for this type of pit shield ground on the theory of limit equilibrium approaches and soil-structure interaction.Simultaneously, the program of FLAC has been adopted to simulated the same example. The calculational model of this thesis has been prowed to be credible again.The result of analysis indicates that the deformation of the wall of pit can be strongly controlled and the stability of the constructional system has favourable stability. Research of thie thesis can make import reference for design of the anchored pile of reinforce cement soil with the shape of"door".
