Computer Program For Winkler Soil-Structu Interaction Analysis of Sheet-Pile Walls (CWALSSI). User's Guide.
Abstract
This report describes the computer program CWALSSI which performs soil-structure interaction (S SI) analysis of sheet-pile walls using the Winkler assumption for representing the soil as nonlinear springs. The program uses classical soil mechanics procedures for determining the limiting active, at-rest, and passive soil pressures. Seepage effects are included in a simplified manner in the program. CWALSSI was developed from specifications provided by the Computer-Aided Structural Engineering (CASE) Task Group on Sheet-Pile Structures. CWALSSI is a companion to Program CWALSHT (CORPS Program X0031) which performs design of anchored or cantilever sheet-pile walls by classical methods. CWALSSI performs no design functions. Design parameters such as depth of penetration, the sheet-pile section, and the characteristics of anchors (if any) must be supplied as input to CWALSSI. The remainder of this report is organized as follows: Chapter 2 describes the general sheet-pile retaining structure and the soil system to be analyzed by the program. Chapter 3 describes the procedures employed in the program for calculating the limiting earth pressures, water pressures due to unbalanced hydrostatic head, and the effects of surcharge loads on the soil surface. Chapter 4 outlines the methods for converting the surrounding soil and anchors to nonlinear springs. (MM)
