Wangcheng Yali Middle School's Compaction Foundation Project: The Wangcheng Yali Experimental School is located at the southeastern corner of the intersection of Dan Gui Road and Lei Gao Road in Wangcheng District, Changsha City. The proposed site is surrounded by already constructed municipal roads, with the south side adjacent to the Yida Town residential area. The compaction foundation treatment project for the Wangcheng Yali Experimental School covers an area of 50,000 square meters, utilizing compaction energy of 1000KN.m to 7000KN.m. The treatment depth within the compaction foundation area has an Es compressibility modulus of ≥5.0MPa, and the characteristic value of foundation bearing capacity is not less than 100KPa.
