How to Use CWALSHT for Designing and Analyzing Sheet Pile Walls
Sheet pile walls are structures that retain soil or water by using interlocking steel or concrete piles driven into the ground. They are commonly used for cofferdams, retaining walls, foundations, and waterfront structures. Designing and analyzing sheet pile walls can be a complex and time-consuming task, requiring knowledge of soil mechanics, structural engineering, and hydrostatics.
Fortunately, there is a computer program that can help you with this task: CWALSHT. CWALSHT stands for Computer Program for Design and Analysis of Sheet Pile Walls by Classical Methods. It was developed by the U.S. Army Corps of Engineers (USACE) as part of the Computer-Aided Structural Engineering (CASE) Project[^1^]. CWALSHT can perform design and/or analysis of either cantilever or anchored sheet pile walls, using classical soil mechanics procedures for determining the required depth of penetration of a new wall or assessing the factors of safety for an existing wall. It can also include seepage effects in a simplified manner[^2^].
In this article, we will show you how to use CWALSHT for designing and analyzing sheet pile walls. We will cover the following topics:
How to download and install CWALSHT
How to input data and run CWALSHT
How to interpret and verify the results
How to troubleshoot common errors
By the end of this article, you should be able to use CWALSHT confidently and efficiently for your sheet pile wall projects.
How to Download and Install CWALSHT
CWALSHT is available for free from the USACE website[^3^]. You can download it as a zip file that contains the executable file (CWALSHT.EXE), a user's guide (IR-ITL-91-1.PDF), and some example files. To install CWALSHT, simply unzip the file to a folder of your choice. You can run CWALSHT by double-clicking on the executable file or by using a command prompt.
How to Input Data and Run CWALSHT
CWALSHT uses a text-based interface that prompts you to enter data for each step of the design or analysis process. You can also use an input file that contains all the data in a predefined format. The user's guide provides detailed instructions on how to prepare an input file and what data are required for each type of wall. The input file must have a .DAT extension and must be located in the same folder as the executable file.
To run CWALSHT using an input file, you need to enter the name of the input file without the extension when prompted by the program. For example, if your input file is named EXAMPLE.DAT, you need to enter EXAMPLE when asked for the input file name. CWALSHT will then read the data from the input file and perform the calculations.
To run CWALSHT interactively, you need to enter N when prompted for an input file name. CWALSHT will then ask you to enter data for each step of the design or analysis process. You can use the default values provided by the program or enter your own values. You can also edit or review any data before proceeding to the next step. The user's guide provides detailed explanations of each data item and how they affect the calculations.
How to Interpret and Verify the Results
CWALSHT produces an output file that contains the results of the design or analysis. The output file has a .OUT extension and has the same name as the input file or as specified by the user. The output file is located in the same folder as the executable file.
The output file consists of several sections that provide information on:
The input data and assumptions used by the program
The earth pressure coefficients and forces acting on the wall
The bending moments, shear forces, deflections, and stresses in the wall
The required depth of penetration or factors of safety for each type of wall
The seepage effects on earth pressures and factors of safety
