Triangle Method
Settlement of terrain behind the shoring structure is calculated according to the following formula in case of triangle method:
where: | δmax | - | maximum settlement |
sw | - | area formed by the deformed structure and un-deformed structure | |
x0 | - | range of settlement |
The range of terrain settlement x0 is defined as follows:
where: | H | - | depth of excavation |
D | - | length of the structure below the bottom of foundation pit | |
φ | - | weighted average internal friction angle of all soil layers that the structure goes through |
