Development of Predictive Equation for Vibration Due to DMC Piling
Abstract Conventional casting of bored cast-in-situ pile which is also known as direct mud circulation (DMC) method was accepted as the most reliable piling system all over the world. Compared to precast pile driving, chiseling action in DMC piling produces low energy. This low energy can produce stress waves in the ground which may cause problems to the adjacent structures. This paper deals with the development of predictive equation for the peak particle velocity (PPV) for different types of soil due to ground vibrations caused during DMC method of piling. Ground vibration analyses were carried out for different soil profiles with different hammer energy impacts. The ground acceleration produced during DMC piling at different distances and depths from the source of vibration were measured on layered soft clay and lateritic soil mediums. The PPV depends on the soil constants k and n. These soil constants for different soil types, such as soft clay and lateritic clay, are compared in this paper. Developed soil constants of DMC piles are then compared with those of driven piles.
