Sheet piles, PZ22, PZ27, PZ35, PZ40

Sheet piles on loads Enter the user defined partial factor applied to the different kind of loads.The maximum moment estimated by the CWALSHT program is 19, 080 feet-pounds and maximum shear of 6, 126 pounds at elevation 77. Preliminary data. The following preliminary information must be established before design of the system can commenceEnter the user defined reduction in height applied to the surface level on the PZ22 passive side.Elevation at the top of the sheet piling. Change in phreatic line on passive side.

The difference PZ22 and PZ27 in the analysis completed by hand calculations, and the CWALSHT analysis is due to the method of estimating the active and passive earth pressure.Enter the user defined change in height applied to the phreatic line level on the passive side.The minimum section modulus of 50 kilopounds per square inch steel per foot of wall.Material factors Enter the user defined partial factor applied to the cohesion, Reduction in surface level on passive side.A CZ–67 PZ 27 pile will provide a section modulus of 10.69 cubic inches per foot of wall. Enter the user defined increase in height applied to the phreatic line level on the active side. Water elevation on each side of the wall and seepage characteristics.The thickness of a CZ–67 is 0.217 inches. A minimum thickness of 0.25 inches is recommended. A CZ–84 provides a thickness of 0.276 inches and section modulus of 13.62 cubic inches per foot of wall.Enter the user defined partial factor applied to: calculated or used during the Overall Stability verification (chapter 32). The soil profile on each side of the wall including location and slope of subsurface layer boundaries strength parameters (angle of internal friction cohesive strength c, angle of wall friction , and wall/soil adhesion) and unit weight for each layer to a depth below the dredge line not less than five times the exposed height of the wall on each side.

The steel sheet pile per foot of wall is:This input is available only if the Check vertical balance check-box was enabled in the Model window (section 4.1.1).The steel sheet pile should be Grade 50 steel with a minimum section modulus of 13.6 cubic inches per foot of wall. (210–VI–NEH, August 2007) TS14R–31. Other assumptions are discussed in the following paragraphs. Raise in phreatic line on active side.The ground surface profile extending to a minimum distance of 10 times the exposed height of the wall on either side.Enter the user defined partial factor on base resistance γb applied on the characteristic value of the base resistance of the ground Rb;k to get the design value of the base resistance Rb;d (Equation 33.1): T(5) Magnitudes and locations of surface surcharge loads. In this tutorial, Phase2 is used to simulate the construction of an excavation supported by a sheet pile wall anchored with grouted PZ40 tiebacks. (6) Magnitudes and locations of external loads applied directly to the wall.Click this button to reset all values to the default values prescribed in CUR 166.

The default PZ35 and PZ40 values prescribed by CUR 166 (CUR, 2005) are written at the left of each input area of the User Defined Partial Factors window. The loads applied to a wall fluctuate during its service life. Consequently, several loading conditions must be defined within the context of the primary function of the wall.If modified, the value appears in red color.Design and Use of Sheet Pile Walls in Stream Restoration and Stabilization. For background information on CUR 166 design method, see chapter 34. As a minimum, a cooperative effort among structural, geotechnical, and hydraulic engineers should identify the load cases outlined to be considered in the design.

The deflection of the top of the PZ 22 and PZ 27 pile may be determined by using the analysis mode of CWALSHT and inputting the actual pile properties or by dividing the scaled deflection provided by the design mode by the modulus of elasticity of the steel and the moment of inertia per foot of pile.The complete model can be found in the Tutorial 23 Anchored PZ35 Sheet Pile Wall.On the menu bar, click Project and then choose Properties to open the input window. The loads associated with this condition are those most frequently experienced by the system in performing its primary function throughout its service life. The Project Properties window contains four tabs, which allow the settings for the current project to be changed.fez file. Title 2 and Title 3 can be added to indicate specific characteristics of the calculation. The three titles will be included on printed PZ 35 output.All tutorial files installed with Phase2 8.0 can be accessed by selecting File > Recent Folders > Tutorials Folder from the Phase2 main menu.Use the Identification tab to specify the project identification data.

Figure 4.6: Project Properties window, Identification tab.The fundamental design of the system should be optimized for these PZ27 loads. Titles Use Title 1 to give the project a unique, easily recognizable name. Open the Project Settings dialog from the Analysis menu and make sure the General tab is selected.Project ID Enter a project identification number. Annex ID Specify the annex number of the printout.The loads may be of a long-term sustained nature or of an intermittent, but repetitive PZ 40 nature. Conservative factors of safety should be employed for this condition.

Date PZ 35 and PZ 40 entered here will be used on printouts and graphic plots for this project. Select the Stages tab and change the number of stages to 5.Close the dialog by clicking OK. Either mark the Use current date check-box to automatically use the current date on each printout, or enter a specific date. Construction and/or maintenance operations may produce loads of infrequent occurrence and are short duration which exceed those of the usual condition.
