Abstract

Tieback retaining walls are using as temporary shoring systems for bridge footings or other structures that need deep excavations. Design and design review process are time consuming, and the possibility of making mistakes encourages us to find a simplified method for designing the tieback walls. Tieback walls with maximum 20m height and with 1 to 4 rows of anchors is considered in this paper. Whole length of the drilled holes will be filled with grout after setting the rods or stressing cables. Sometimes for temporary shoring the rod will be anchored to a concrete block supported by dirt, so there would be no need to grout the hole. Steel plate or wood timber lagging or steel mesh along with shotcrete will be used between the shoring piles (soldier piles). The simplified KZP6 method is based on the soil mechanic concepts for the granular and cohesive soils and the Boussinesq strip load method for the possible surcharge behind the wall. In this paper besides considering the simplified method (KZP6) an example will be solved based on our simplified method and will be compared with the conventional method results to show the accuracy of the results.

The Simplified KZP6 Method For Tieback Wall Design in Granular and Cohesive Soils

Chicago, Illinois

Tieback retaining walls are using as temporary shoring systems for bridge footings or other structures that need deep excavations. Design and design review process are time consuming, and the possibility of making mistakes encourages us to find a simplified method for designing the tieback walls. Tieback walls with maximum 20m height and with 1 to 4 rows of anchors is considered in this paper. Whole length of the drilled holes will be filled with grout after setting the rods or stressing cables. Sometimes for temporary shoring the rod will be anchored to a concrete block supported by dirt, so there would be no need to grout the hole. Steel plate or wood timber lagging or steel mesh along with shotcrete will be used between the shoring piles (soldier piles).
