Investigation of applicability of deep-whisking-stake to handling saturated loess groundwork

Through illustration of an engineering practice, the feasibility of appplication of deep-whisking-stake to reinforcing saturated loess is emphatically discussed by using both the experimental and typical construction data and it is shown that the method presented is fairly good one for handling the saturated loess groundwork. It is also shown in the meantime that the solidity of cement-erath mixture can be greatly improved by addition of adscititions dosage into the mixture. It has been two years since the project being completed while there is no distortion with the grundwork, manifesting the success of the method for practical application.
