USER'S GUIDE: COMPUTER PROGRAM FOR DESIGN AND ANALYSIS OF SHEET PILE WALLS BY CLASSICAL METHODS (CSHTWAL). REPORT 1. COMPUTATIONAL PROCESSES

This report describes the CSHTWAL computer program used for design and analysis of either anchored or cantilever sheet pile retaining walls. The program is written for interactive use from a remote terminal. Stratified soil profiles, irregular ground surfaces, arbitrary water levels, and a variety of vertical and horizontal external loads are permitted in the description of the wall-soil system. Net pressures on the wall are determined either by Coulomb coefficients or by a wedge method. Effective soil internal friction angle and effective soil cohesion are used for development of pressures. The program determines the required penetration for a given factor of safety; or, in the analysis mode, the factor of safety is determined for a given penetration. The conventional procedure for calculation of design penetration is used for cantilever walls. Five alternative procedures (free earth, fixed earth, equivalent beam, equal moment, and Terzaghi) are available for investigation of anchored walls. Output from the program consists of a summary of results containing design penetration or factor of safety with maximum bending moment, maximum relative deflection, and anchor force. A complete tabulation of net soil pressures, bending moments, shears, and deflections is available at the user's option. Example solutions and supporting verification of results are provided.
