The Influence to Modal Parameters of Retaining Wall by the Elastic Modulus of Soil
The characteristic of soil is one of the main factors that influence the modal parameters of retaining wall. This paper analyzes the influence to modal parameters of retaining wall by the elastic modulus of soil. Due to the complexity of the interaction of soil and retaining wall and based on the three-dimensional numerical test, dynamic response signals of retaining wall are obtained, processing of which and identification of modal parameters lead to the modal parameters of retaining wall. Lastly, vibration characteristic, frequency characteristic and the relationship of frequency and elastic modulus are also obtained.Therefore, the real elastic modulus of soil is gained by response signals in practical projects, and the degree of soil compaction can be pre-judged.
