USE OF CHARTS FOR RELIABILITY-BASED DESIGN OF EMBANKMENTS ON SATURATED CLAY LAYER

Work on reliability-based designs in the field of geotechnical engineering is considered to encounter two main difficulties - the calculation of the probability of failure and the resistance to alternative design methods. The article discusses a study intended to overcome the first difficulty. The optimum design of an embankment constructed on a saturated clay layer is discussed and details are given of charts designed to indicate the probability of failure. In order to overcome the second difficulty a procedure is introduced to determine the probability of failure based on safety factor so that results of the reliability-based design can be compared with other methods. Loss functions to estimate design alternatives are also evaluated and examples are given of optimising embankment design. Results are discussed comparing those obtained with traditional safety factor methods. (TRRL)
