摘要

A three phase program involving laboratory and field investigation was used to test a new synthetic fabric, Acrilan, designed to be used in the form of soil-filled 'sand-pillows' for reservoir bank or slop protection from wave erosion. Irrigation reservoirs in the Midwest often have severe erosion problems due to the lack of quality control during construction, the flat topography with little wind shelter, and the fine-grained quality of the soil. Acrilan has several advantages over other slope protection materials: (1) outstanding biodegradation and ultraviolet light resistance, (2) ease and economy of installation, (3) ease of repair, and (4) excellent cost/benefit relationships. The sand pillow system with Acrilan was modeled to evaluate the parameters that affect the stability of the pillows when placed on an embankment slope. Modeling results were used to develop design criteria for the individual pillows. Soil retention ability of the fabric was tested by laboratory immersion tests where the fabric was subjected to constant wave action. The field tests were conducted on a pump-in irrigation dam in north central Missouri. Erosion rates of unprotected sections were compared with rates on protected sections of the same embankment. Results show that sand pillow stability is primarily a function of wave height, wave period, embankment slope angle, and pillow weight. The sand pillow method offers excellent slope protection, however, due to loss through the fabric, some limiting minimum particle size specification is needed.
