Research On Mechanical Properties Analysis Of Highway Pile Retaining Wall

With the rapid development of China’s highway projects in the western mou ntain region,increasingly high for the requirements of the roadbed of security and stability.A large number of retaining structures used in the construction of the mountain road.In the drawing based on bridge engineering foundation design theo ry, pile retaining wall of this structure in the engineering and technical personnel used in the design of the mountainous terrain roads. This paper focuses on pile retaining wall for studying. Through summarizing the existing pile retaining wall design calculation and finite element numerical simulation analysis the pile foun dation of mechanical properties of retaining structure.On the basis of previous research results and practical engineering projects, this paper focuses on the following aspects:First, the summary of the design of retaining walls to calculate the theory, design of pile caps to calculate the theoretical calculation theory and design of pile foundation; Second, according to the use of pile retaining wall the actual projects, the pile retaining wall for different operating conditions in the finite element numerical software in Plaxis8.5corresponding simulation model and numerical simulation and analysis of calculation results;Third, the actual engineering design of highway engineering projects in the pile retaining wall structure design calculation process analysis and the actual calculations and numerical simulation results of a comparison.Using reference and practice a combination of line, in-depth study of the application of the pile wall in highway engineering design and calculation of theoretical and numerical calculation methods, and some of the conclusions and methods for the mountain region highway construction to provide reference.
