some researches have dealt with soft foundation using vacuum preloading-electroosmosis method which can only discharge partial weakly bound water in soft soil
but the amount of postconstruction settlement is still too much to meet the requirements of engineering. To solve this problem
a small amount of salt solution was added on the basis of vacuum preloading-electroosmosis method
known as vacuum preloading-electrokinetics method
and achieved a better experiment result. The soft soil in the pearl river delta region was studied. The comparative test was used between vacuum preloading-electroosmosis method and vacuum preloadingelectrokinetics method(adding Cacl

solution) in soft ground treatment
and it came to a conclusion that vacuum preloadingelectrokinetics method is at an advantage when dealing with soft soil
which provided a scientific basis for applications of vacuum preloadingelectrokinetics method.
