Use the form heap to indicate whether the quantity is calculated. To assign material to the model, select properties to specify properties. In the definition of net pressure distribution, positive pressure tends to move the wall toward the mining side. Typical net pressure diagrams, such as stress, displacement, moment and lateral force, are shown. Please check the PZC13 and PZC14 phases. By default, all content is set to Sand material. Stability design of cantilever wall sheet pile manufacturers. Suppose the cantilever wall revolves around a point in its embedding length as a rigid body, as shown in figure 5-2a. The ratio display is based on the maximum value of each phase (OFF) or the maximum value of all build phases (ON). This assumption implies that the PZC 19 or PZC 25 wall is subjected to a net effective pressure distribution from the top of the wall down to a point near the zero displacement point (later called the "transition point").
Use steel sheet pile to specify the graphical display of calculation results. Select Clay from the Allocation dialog box, and then click the model section below the green material boundary. Item Properties window, Chart Settings tab Layer Boundary and then assume that the design pressure distribution varies linearly from the net effective pressure at the transition point to the net passive pressure at the bottom of the wall. In the second stage, PZC 14 and PZC 18 will increase support, so the material has not changed. In the third stage, we will start digging. Click the Stage 3 tab. Mark this check box to display the dashed line between the soil boundaries. This will set the initial state of the first stage. The material color is marked with this check box to display materials in different colors.
The drawing layer shows the design pressure distribution across the width. Selecting this check box can draw a layer on the entire width of the chart. The envelope shows the whole body picking PZ 25 from the Specify menu and clicking on the top left of the model, as shown in Figure 1: The balance of the wall requires that the sum of horizontal forces and moments at any point must be equal to zero. In our model, sheet pile walls are sandwiched between two joints. The data will be displayed in the main windows of PZC18 and PZC19 SHEET PILING. Click the print activity window icon to print the file. Walls and joints form a structural interface. Right click the structure interface (dark green line) and select "structure interface properties". Each new analysis starts with data input from PZ 19 sheet pile, composite wall, single pile or partition wall. These data will apply to every construction stage. Two equilibrium equations can be solved for the location of the transition point and the required penetration depth. Since the simultaneous equations are nonlinear in Z and D, trial and error methods are needed.
Check this check box to show the potential water level (right and left) and different levels of markings. Many years of research and experience show that the wall designed by free earth method is stable enough, and its permeability is lower than that designed by fixed earth method. The PZC 13 sheet pile wall will be installed in the second stage, so click the tab to display the second stage. On the menu bar, click Construct, and then select Sheet Pile to open the input window for regular PZ 18 Sheet Piles. You can also create composite walls through special guides. Now you'll see a dialog box that provides the default properties for the liner (wall) and two joints.
It is classified as a variant of the "free earth" method and the "fixed Earth" hypothesis. Only when the PZ25 sheet pile driving model in the Model window is selected can the PZ19 sheet pile driving window be used in the Structure menu. Due to the flexibility of the PZ 13 sheet pile, the Free Earth method can predict larger moments than the actual ones. The torque reduction curve using Rowe overcomes the shortcoming of the free earth method, as described in the sixth chapter. For elastic or plastic calculations, the contents of the windows will be different. PZ 14 sheet pile elastic calculation. In the free earth method, the PZ18 anchor is assumed to be a rigid simple support around which the wall rotates as a rigid body. This option allows you to select the name and flexural rigidity of the section from the library.
