The invention provides a ground-effect vehicle capable of shallowly diving, which can dive shallowly to hide water-
jet propulsion and rise over the sea surface to increase 
jet propulsion, changes hydrofoils into airfoils, generates ground effect, flies over sea or very closely to the ground, and lands in a jet traveling manner. A multistage double circular-arc gear 
high pressure large capacity pump or multistage internal serial connection dual-charging double circular-arc 
gear pump is taken as the hydraulic 
propeller pump during the shallow diving process and the jet 
propeller pump during the process of flying over the sea. A water pump is used for water inlet submergence and water drainage to a 
ballast water tank besides 
water jet; when 
jet flow is performed at the 
tail part, and one side is shut off, namely, steering is realized; when flying over the sea, the ground-effect vehicle is still closely stuck to the sea surface for water-
jet propulsion. The jet 
propeller pump can be used for jet propulsion at the 
tail part and jet hovering at the bottom part through a valve, and the jet at the 
tail part is turned, so that the purpose of changing the heading can be achieved. The ground-effect vehicle has four navigation conditions: main water-jet shallow diving; main water-jet and jet flying over the sea; minor jet flying near the ground; and minor jet traveling wheel landing, and the ground-effect vehicle is manufactured by manly adopting a novel light material, for example, the 
fiber reinforced 
composite material (FRP).
