Studies on Geology of the Backfilling Fly Ash and the Foundation Treatments

Abstract:

Whether the site of backfilling fly ash was appropriate for engineering geology, and how to use effective means to change the geologic bearing capacity of the site were urgent solving problems. This work took a site of backfilling fly ash in the Beishiwang Village, Yindu District, Anyang City, Henan Province as object of study, detailedly did a complete geologic survey on it, got related data and made its engineering geologic assessment and according to the characteristics and requirements of construction projects, we select the most optimal treatment means of the foundation and adopt the most safe and economic perfusion pile with post-pressure grouting to strengthen this engineering foundation.
