Due to The Vast Territory of China, The Topography, Geological Conditions and Surrounding Environment of the Construction Project are Very Different. The Design and Construction of the Foundation Pit Support Project is One of the Most Closely Integrated Engineering Measures Combined with the Above Conditions. The Design and Construction of Deep Foundation Pit Support Engineering in Special Geotechnical Areas Has Become One of the Most Complicated Technical Problems in the Field of Civil Engineering Construction. Based on the Above Background, The Purpose of this Paper is to Study the Foundation Pit Support Structure Under Special Geotechnical Structure. This Paper Compares and Analyzes the Materials and Structure Types that Can be Used for Foundation Pit Support, And Concludes that Bamboo is an Economical and Environmentally Friendly New Material, Its Output Large, Good Mechanical Properties, Can Be Used For Temporary Support of Shallow Foundation Pits. It is Proposed to Use the Bamboo Tube as the Foundation Pit Support Material, And it is Applied in the Soft Soil Layer Foundation Pit Support Project in the form of Row Pile Support Structure. In this Paper, the Top Displacement of the Bamboo Pipe Pile is Larger than that of the Steel Pipe Pile, But the Maximum Pile Top Displacement of the Bamboo Pipe Pile is 1.8mm. The Maximum Displacement of the Pile Top is 18mm, The Displacement is Small, Within the Allowable Range, and in the Actual Project, the Pile Top is Generally Constrained to Further Control the Displacement of the Pile Top to Ensure the Safety and Stability of the Foundation Pit.
