Further Improvement of Vacuum Combined with Surcharge Preloading Method in Engineering Applications

The further improvement of vacuum combined with surcharge preloading method was introduced in the practical application of engineering: the roadbed was constructed by one-step using the vacuum combined with surcharge preloading method in the municipal roads.The practical application of this project shows that: it can reduce the roadbed construction costs,shorten the construction period and reduce the settlement after construction,and provide the basis for similar projects.
