%X In this paper, the current status about the tests on swelling strains of expansive soils is analyzed. Formulas are derived, which can be used to calculate the linear swelling ratio between moisture content and upper load for expansive soils by adopting lateral restricted swelling experimental data for expansive soils in Ningming section of Nanning-Youyiguan road,in case of lateral confinment and upper loads, based on the relationship between upper loads and linear swelling ratio, the relationship between upper loads and end moisture content and the relationship between process moisture content and water absorption content. Some comments are put forward about embankment construction of expressway from Nanning to Youyi gate.
