Deep dynamic compaction vibrations impacts on neighboring structures.

Abstract

This paper describes results from vibration study conducted for a construction of proposed building structures on a covered landfill site. Construction site is surrounded by various land uses, including mobile homes, single dwelling units, and infrastructures. Deep dynamic compaction (DDC) method is utilized to provide soil compactions necessary for the construction of the buildings and parking lot foundations. Concern with the potential structural damage and the human perceptions of the ground vibration exist because of close proximity of the existing structures (i.e., mobile homes, single homes, roadways, and bridges) to the compaction area. DDC induced ground-vibrations level were modeled using actual vibration measurements “pilot tests” and the site’s soil dynamic characteristics. Vibration mitigation plan were developed to minimize the impacts.
