In regard to Zhonglan Real Estate Residential Land Project, analysis of the formation mechanism of “rubber soil” led to the conclusion that treatment of “rubber soil” is to change the flow-plastic properties of “rubber soil” and reduce the moisture content in the soil layer. The measures to change the flow plasticity of soil layer include replacing with different soil, adding cement and quicklime with deep mixing to enhance the consolidation performance, or pressing in gravel and pebble to increase the stability. The measures to change water content include replacement with different soil, digging and drain water to dry, dewatering with pumping. For this project, mixing replacement and dewatering with pumping has been performed to achieve the purpose of eliminating the “rubber soil” characteristics, which met the requirement for construction ground.
