PLAXIS 2D Tutorial 03: Dry excavation using a tie back wall

20 May 2017

This example involves the dry construction of an excavation. The excavation is supported by concrete diaphragm walls. The walls are tied back by prestressed ground anchors.
PLAXIS allows for a detailed modelling of this type of problem. It is demonstrated in this example how ground anchors are modelled and how prestressing is applied to the anchors. Moreover, the dry excavation involves a groundwater flow calculation to generate the new water pressure distribution. This aspect of the analysis is explained in detail.

The attached *.p2dxlog file contains all the commands to generate the model. With a PLAXIS VIP licence, you can use the commands runner to open the *.p2dxlog file and to execute all commands in one go, see also this instruction.
