Abstract
Comparing with the domestic projects, there are many different constraints for the Vacuum-surcharge preloading design of soft sub-grade condition in Vietnam projects, and also there are not any relative available codes or standards to use. Based on the special condition in soil improvement design in Vietnam, the article proposes to supplement the geotechnical investigation and soil test, and give the analysis and control methods of key technique about the design of new horizontal drainage system, clay sealing wall, vacuum system, theory settlement calculation, and the application of monitoring data. Finally, the settlement, degree of consolidation and bearing capacity of the soft soil layer can all meet the requirement in contract after soil improvement.关键词
