Use sheet pile to indicate whether the calculated quantities. To assign the materials to the model, select Properties → Assign Properties. In these definitions of net pressure distributions, positive pressures tend to move the wall toward the dredge side. Typical net pressure diagrams are illustrated, such as the stresses, displacements, moments and transverse forces. Be sure you are looking at the PZC13 and PZC14 stage. By default, everything is set to Sand material. Stability design for cantilever walls. It is assumed that a cantilever wall rotates as a rigid body about some point in its embedded length as illustrated in Figure 5-2a. are to be displayed using a scale based upon the maximum values for each phase (OFF) or the maximum values over all construction stages (ON). This assumption implies that the PZC 19 or PZC 25 wall is subjected to the net active pressure distribution from the top of the wall down to a point (subsequently called the "transition point") near the point of zero displacement.

Use steel sheet pile to specify the display settings for the graphic representation of calculation results. Select Clay from the assign dialog and click in the sections of the model below the green material boundary. Project Properties window, Chart Settings tab Layer boundaries The design pressure distribution is then assumed to vary linearly from the net active pressure at the transition point to the full net passive pressure at the bottom of the wall. In the second stage, PZC 14 and PZC 18 will add support so there is no change in material. In the third stage we will start excavating. Click on the Stage 3 tab. Mark this check-box to display dotted lines between soil boundaries. This sets up the initial state for the first stage.Material colors Mark this check-box to display material using different colors.

Draw layer over full width The design pressure distribution is illustrated. Mark this check-box to draw layers over the full width of the chart. Envelope displaying overall Choose PZ 25 Excavate from the Assign menu and click inside the top left section of the model as shown: Equilibrium of the wall requires that the sum of horizontal forces and the sum of moments about any point must both be equal to zero. In our model, the sheet pile wall is sandwiched between two joints. The data will be displayed in the PZC18 and PZC19 SHEET PILING main window. Click on the Print Active Window icon to print the file. The wall plus the joints together make up a structural interface. Right click on the structural interface (dark green line) and select Structural Interface Properties. Every new analysis starts with the input of data on the PZ 19 sheet piling, combined wall, single pile or diaphragm wall. This data will apply to every construction stage. The two equilibrium equations may be solved for the location of the transition point and the required depth of penetration. Because the simultaneous equations are nonlinear in z and d, a trial and error solution is required.

Mark this check-box to display the markers of the phreatic levels (right and left) and the different layers levels. Research and experience over the years have shown that walls designed by the Free Earth method are sufficently stable walls with less penetration than those designed by the Fixed Earth method. The PZC 13 sheet pile wall will be installed in Stage 2 so click on the tab to show Stage 2. On the menu bar, click Construction and then choose Sheet Piling to open the input window for regular PZ 18 sheet piling. Combined walls can also be generated via a special wizard. You will now see a dialog that gives the default properties of the liner (wall) and the two joints.

Classified as the "Free Earth" method and variations of the "Fixed Earth" hypothesis. The PZ19 Sheet Piling window is available in the Construction menu only if the PZ25 Sheet piling model in the Model window is selected. Because of the flexibility of the PZ 13 sheet piling, the Free Earth method predicts larger moments than those that actually occur. This shortcoming of the Free Earth method is overcome by using Rowe’s moment reduction curves, as described in Chapter 6 The content of the window will be different for an Elastic or a Plastic calculation. PZ 14 Sheet Piling – Elastic Calculation. In the Free Earth method, the PZ18 anchor is assumed to be a rigid simple support about which the wall rotates as a rigid body. This option allows the name and bending stiffness of the section to be selected from a library.

Despite the tendency of the wall to produce a passive condition in the retained soil above the anchor, it is assumed that the wall is only subjected to the net active pressure distribution as illustrated. First, the top level of the sheet piling is entered. Next, click the Insert row button to insert a new row or click the Add row button to add one. In Stage 4 we will install another PZ14 tieback and excavate further. Click on the tab for Stage 4 and then click inside the next area to be excavated. The library contains the standard profiles of different manufacturers and additional user-defined ones. After the depth of penetration has been determined, the PZC25 anchor force is obtained from equilibrium of horizontal forces. Because the position of the anchor affects both depth of the stiffness and/or acting width for each section can be varied. Alternatively, use the PZ13 Paste icon to paste the complete content from an external source into the table. Name The default name of the section can be changed here if desired. The required depth of penetration is determined from the equilibrium requirement that the sum of moments about the anchor must be zero.
