Bridge bumping is a key generic technological problem in bridge constructions. Weak foundation and additional stress are caused by filling materials and rigid-flexible mutation. Traditionally, complex reinforcements for soft soil foundations are adopted with little efficiency. As a new type of lightweight man-made soil, foamed lightweight soil with a light bulk density and adjustable unconfined compressive strength can effectively solve this problem. A typical design method of bridge head with foamed lightweight soil is presented and discussed in this study. The main mechanisms of foamed lightweight soil in mitigating the influence of different stiffness of abutment and soft soil are analyzed accordingly.
