Fill Placement Rates for Highway Embankments
The project is concerned with the development of techniques to optimize fill placement rates for the construction of highway embankments on soft soils. It is intended that the end product and major contribution of this work be a series of charts and computer programs which the practicing engineer may employ as guidelines in establishing (a) a suitable rate at which a highway embankment resting on a layer of soft soil may be preloaded without exceeding the bearing capacity of the soft layer, and (b) the associated settlements. The study involves consideration of the stress and shear strength distributions below the embankment, the process of consolidation, and the bearing capacity of the subsoil. Details of these component problems are discussed. Primary effort is being directed toward the utilization of information already reported in the literature. This interim report discusses the model problem, the theoretical assumptions and practical limitations concerning stress distribution, distribution and dissipation of excess pore pressure, consolidation theory and its numerical treatment, effective stress and strength gain, stability criterion and settlement. The report also describes the steps taken in the development of appropriate computer programs. Flow charts are presented. (BPR abstract)
