摘要

Every embankment project is unique. In addition, design procedures and templates are not well codified and standardized. A "checklist" for designers and reviewers may prevent overlooking critical aspects of a design because designs are not standardized. This article presents a "checklist" that highlights some of the important aspects of the geotechnical issues in the design of embankments. The Author developed the checklist based on 39 years of experience in design of small earth embankments. Examples of topics included in the paper include: 1. Are the specifications for degree of compaction appropriate considering the size of the embankment and the zone in the dam for which the specifications are written? 2. Could the specifications for placement water content allow compaction of soils to undesirable conditions? Specifically, would they allow a brittle over-compacted condition in the soils? Has the natural water content of the borrow soils been considered? 3. Is an embankment chimney filter or filter diaphragm part of the design? If not, does the design documentation adequately justify the elimination of these features? Examples of justification are a lack of differential foundation settlement, erosion resistant, non-dispersive embankment soils, and placement recommendations for wetter than normal compaction. 4. Have suitable quality control procedures been specified for construction, particularly the method of selecting reference compaction tests values? Has a quality control plan been made part of the construction effort? 5. Is the proposed cutoff measure a complete cutoff of seepage? If not, have adequate drainage and filters been included in the design to address uplift and critical discharge gradients? 6. Has differential settlement been evaluated and defensive design measures included in the design if the differential settlement is excessive? 7. Critical questions that should be asked in evaluating shear tests are discussed 8. Have tests been performed to evaluate problematic embankment and foundation soil types? Examples are tests to identify dispersive clays, collapsible soils, sands susceptible to liquefaction, and others.
