PLAXISCONNECT Edition 2D - Tutorial Manual - Dry excavation using a tie back wall [ADV]Last Updated: March 16, 2021 1 Dry excavation using a tie back wall [ADV]This example involves the dry construction of an excavation. The excavation is supported by concrete diaphragmwalls. The walls are tied back by prestressed ground 2D allows for detailed modelling of this type of problem. It is demonstrated in this example how groundanchors are modelled and how prestressing is applied to the anchors. Moreover, the dry excavation involves agroundwater flow calculation to generate the new water pressure distribution.
Mar 16, 2021 · Although the precise stress state and interaction with the soil cannot be modelled with this 2D model, it is possible in this way to estimate the stress distribution, the deformations and the stability of the structure on a global level, assuming that the grout body does not slip relative to the soil. With this model it is certainly not
