Sheet pile PU11R PU13R is available only for steel piling PU14R PU15R model.Heaving In Soft Clay - For construction in soft clay, heave at the bottom of the PU11R excavation may occur, resulting in PU13R settlement of the surrounding ground surface. On the menu bar, click Loads and then PU14R choose Surcharge Loads to open the PU15R corresponding input window.The conventional method of analysis for investigating heave was developed by Terzaghi13 and is illustrated in Figure 60.

Steel piling PU 11R PU 13R surcharge acts on the PU 14R soil surface to PU 15R the left or right of the sheet pile wall. In this case, the vertical column of soil along the sheeting is assumed to exert a pressure on the horizontal plane A-A’.Enter value of the load at several distances from PU 11R the sheet pile wall.When the pressure exerted by this soil column exceeds the bearing capacity of the soil beneath PU 13R the sheeting a bearing type failure will occur, resulting in heave of’ the bottom of the excavation and settlement of the surrounding PU 14R ground surface. Between these points, linear interpolation is used. Up to 10 surcharge loads can be added. Based on this PU 15R failure model the depth of excavation at which heave will occur can be expressed by.
