| Abstract: | Composite improving program of cement and lime is selected to dispose of saline soil.The full water of unconfined compressive strength is chosen to evaluate whether the improving program is good.The full wa-ter of unconfined compressive strength test aims at improving saline soil of different improver doses and differ-ent curing age,and scanning electron microscopy(SEM)is used to analyze the micromechanism of improved saline soil.Finally the benefit-cost ratio method is applied to evaluate whether the impro... |
