- Abstract
- This report presents the results of ongoing studies aimed at developing a rational design method for reinforced earth retaining walls. The described method is based on results obtained from small laboratory scale walls subjected to horizontal sinusoidal loading with a shaking table. Tests show that the walls respond like a non-linear damped elastic system to the input vibrations. From measurements of the peak tie forces, an empirical design force envelope was developed which is a function only on input acceleration. It is suggested that the design earth pressures for an actual wall subjected to earthquake loading be based on this design force envelope using a base acceleration determined by response spectra modal participation factor techniques. Data are also presented of soil-tie friction under static and vibratory loading. Redommendations are given for calculating the size and spacing of ties including appropriate safety factors. The report is divided into pseudo static studies, vibration studies, and a summary paper.
