Index Method
Settlement of terrain behind the shoring structure is calculated according to the following formula in case of index method:
where: | δmax | - | maximum settlement |
sw | - | area formed by the deformed structure and un-deformed structure | |
x0 | - | range of settlement | |
δ(x) | - | settlement at each point within the range of settlement x0 in distance x | |
x | - | distance between the calculation point and the edge of the foundation pit |
Note: Calculation method for the range of settlement x0 is as same as in case of triangle method.
