Abstract：Through theoretical analyses and site model testing and experiencing, this paper puts forth the design of combined method of vacuum-surcharge preloading in treating deep and soft foundation of high-speed railway, its construction techniques and effects to surround environment. Some key techniques, such as effective consolidation depth , settlement control after projection and measures to control affecting on surrounding environment , etc. , are solved to some extent. The results obtained are important to develop and perfect the mechanism of vacuum preloading in consolidating soft foundation , The forecast of post -construction settlement indicated: it can satisfy the request of settlement 10 cm and settlement 5 cm after vacuum unloading the latter 1 month and II months. This method is the highly effective low price soft ground processing method and can effectively reduce the post-construction settlement to achieve the preloading and overload, and the advantages as followings: fill earth quickly; short construction time and preloading, processing depth bigger, and so on
