This paper proposes two special tools for design of steel sheet pile walls, based on a combination of a subgrade reaction model and the transfer matrix method. In the first tool a plastic hinge is generated when the ultimate moment in the retaining structure is exceeded and earth pressures are redistributed until new equilibrium is found. The program computes the rotation of the plastic hinge, which can be checked with the rotation capacity of the sheet pile in accordance with Annex E of ENV 1993-5 (CEN, 1997). The second tool can be used to study the amount of loss of strength and stiffness due to oblique bending of sheet pile walls composed of double U-sections and to examine the effectiveness of possible measures to reduce the oblique bending. Application possibilities of both tools are illustrated with a typical example.

The new design procedure for steel sheet pile walls from Eurocode 3 part 5 (CEN, 1997) demands the development of simple design tools with a short calculation time which take effects due to the generation of plastic hinges and oblique bending into account. Analysis of plastic hinges is interesting because it involves a possible material saving up to 30% (Van Tol and Kort, 1997) and a tool to study oblique bending is useful to investigate the possible loss of stiffness and strength of the sheet pile. Subgrade reaction models are popular for simple retaining wall design because they give the designer insight in the soil-structure interaction problems, have a short calculation time and offer the possibility to account for rather complicated construction stages. With the second tool the amount of loss of strength and stiffness due to oblique bending can be determined as well as measures to reduce the oblique bending.

This paper investigates the mechanism of slope displacement using the results of long-term monitoring of the unstable behavior and failure of a large excavated rock slope with an elevation difference about 300 m. The study also evaluates the influence of joint sets on slope behavior through numerical analysis. Then fundamental points regarding the stability of large excavated rock slopes are introduced as follows. The stability of a large excavated rock slope is greatly influenced by the joints and weak layers in the rock, and the relationship between their positions and the positions of the excavated surface. It is important not to fail to notice signs of instability caused by the influences of them early through long-term monitoring started in the early stages of excavation. Based on such monitoring, the need of actions should be determined such as additional investigations, stability analysis, and design modifications and changes.

This paper focuses on a case of failure of a large excavated rock slope with a height (an elevation difference) about 300 m. First, the behavior of each part of the slope is analyzed based on the displacement measurements obtained during a period of about 10 years before the failure. Next, each cross section of the slope is modeled by elasto-plastic equivalent continuum analysis to illustrate that the measurements are explainable. And how the unstable behavior of the slope occurred according to the topographical and geological conditions of the respective cross sections is examined.

Geological structure The slope involved in this case study consists of late Paleozoic to early Mesozoic olistostrome: limestone, shale, tuff, and sandstone. The alterations of shale and tuff include lenses of sandstone, and these layers are overlain by olistoliths of limestone.
