Application of Permanent Retaining Wall in Anti-floating Scheme of a Project
Based on the actual site elevation differences and the type of foundation pit support,the project adopted a combined anti-floating scheme with permanent retaining walls and anti-floating anchors.The cast-in-place piles of the foundation pit were designed to serve as per-manent retaining walls,and the sloped excavated sections were separated from the surrounding area by gravity retaining walls,thereby blocking the groundwater seepage pathways from surrounding area that was higher than the project and reducing the anti-floating water level.This anti-floating scheme had achieved good economic benefits and effectively reduced the period of construction.
