How to draw the plane of retaining wall foundation pit

1. Firstly, according to the specific situation, the position of wall toe is determined through technical and economic comparison.

2. Secondly, measure the longitudinal ground line of wall toe, check the cross section of subgrade and collect the geological and hydrological data of wall toe.

3. Then choose the filler behind the wall, and determine the physical and mechanical calculation parameters of the filler and the foundation calculation parameters.

4. Secondly, design the section form, structure and material of retaining wall, and determine relevant calculation parameters.

5. Then arrange the retaining wall longitudinally.

6. Secondly, the section size of retaining wall is determined by calculation method or application of pile diagram.

7. Finally, draw the elevation, cross section and plan of the retaining wall.
