The principle of treating low water content of collapsible loess with ultra high energy level dynamic paction is discussed.The test results show that firstly when the paction function increase the dry density is bigger and the corresponding water content is small;secondly in a certain space of tamping under higher paction energy level and more paction times the paction function will be greater;thirdly the function of ultra high energy level dynamic paction is nearly two times of that of the heavy paction ...
