Abstract:

With expending the cities we need to construct high structures tunnels and subway that all of them have excavation procedure. In construction of excavation operation in the condition that the around space are not limited economical method for safety the excavation walls is constructed of that as slide but in the other hand they do not have a way unless than safety structure. This kind of structure has many kinds like anchored structure with horizontal clams that is a cheep way for constructing the excavation. In designing of anchored excavates with horizontal clamps because of the distribution of pressure in behind of the wall they use the zahery--- pressure diagrams. TARZAGI AND PEK methods diagrams are the famous diagrams. In this paper with making use of these diagrams they provided the diagrams for appointment of forces and maximum moment In the wall. This diagrams are used in 3 way: many kind of the soils look like: sandy, SILTY, 3 kind of loading , the pressure behind of the wall and the basement pressure under ground. The other of the diagrams are provided for appointment the place of the moment in the wall. In the end the experimental methods are compared with the really methods. With the results we see that using the experimental method in dept excavates are suitable.
