Finite Element Analysis On Vertical Bearing Capacity Of Structure Of Waste-tire Foundation

Nowadays,with the rapid rise of the modern automobile industry and the rapid development of the economy,a large amount of our country's land resources are occupied by a large amount of waste rubber tyre,"black pollution" is also polluting our environment.In recent years,many scholars are studying the application of waste rubber tyre solid wastes in civil engineering in order to achieve the purpose of the waste.This paper proposes a novel artificial foundation for rural construction in the structure of waste-tire foundation,due to the weakness of the most of the domestic rural economic conditions and the lack of disaster prevention and corresponding design calculation standards,it is difficult to guarantee the quality and the safety of rural building,so the rural buildings have great potential safety hazard.In this paper,the structure of waste-tire foundation is a simple,reliable bearing,convenient construction and low-cost structure,complex design calculation and construction technology is not necessary for the structure of waste-tire foundation,so this foundation structures can widely inprove the safety of the rural buildings and greatly use the waste-tire,this new type of artificial foundation form-structure of waste-tire foundation can be widely used by the rural buildings in our country.This paper use the finite element software ABAQUS to study the structure of waste-tire foundation's additional stress distribution and the bearing capacity.The structure of waste-tire foundation are compared with natural foundation and other forms of artificial foundation;at the same time,the different factors of the structure of waste-tire foundation are studied to realize the influence of additional stress distribution and bearing capacity,the failure mode of the structure of waste-tire foundation is proposed to study the theory calculation method of of ultimate bearing capacity of the structure of waste-tire foundation.This paper's main research content is as follows:(1)In the paper,the theoretical calculation method of additional stress and ultimate bearing capacity of the non-homogeneous foundation is summarized,which provides theoretical basis for the theoretical calculation of the ultimate bearing capacity of the structure of waste-tire foundation.(2)Based on ABAQUS finite element software,the additional stress and bearing capacity of the structure of waste-tire foundation are compared with other forms of artificial foundation analysis to verify the feasibility of the structure of waste-tire foundation.(3)Based on ABAQUS finite element software,different factors of the structure of waste-tire foundation are studied to realize the influence of the additional stress distribution and bearing capacity of the structure of waste-tire foundation.Which optimal form of the structure of waste-tire foundation shuold be chosen is important in engineering.Optimal form of the structure of waste-tire foundation provide theoretical guidance in the practical engineering application.(4)Based on ABAQUS finite element software,the failure modes of the structure of waste-tire foundation under the ultimate bearing capacity of foundation soil are summarized.According to the theory of ultimate bearing capacity of foundation,the calculation method of ultimate bearing capacity of the structure of waste-tire foundation is derived to provide theoretical guidance and practical engineering applications.
