| Abstract: | Based on the application of construction technique of improved soft ground reinforcement with dewatering and preloading for the vacuum well point in practical engineering,the effect of this technique,the effective reinforcement depth and the change of effective stress were studied through observing the construction settlement in practice and analysing from theory.The applicability of the technique was validated in cold area.The changing regularity of reinforcement effect and settlement were analysed by adopting this technique,which provides some references for the base design and engineering construction. |
