Claim 0:
1. An experimental apparatus for researching characteristics of a subsea tunnel at a bottom of a seabed under a wave, comprising
a main control system,
a wave making test system,
a rock and soil confining pressure test system and
a water level regulation test system,
wherein a bottom of the rock and soil confining pressure test system is connected with the water level regulation test system;
a bottom of the wave making test system is connected with the rock and soil confining pressure test system;
the wave making test system, the rock and soil confining pressure test system and the water level regulation test system are all electrically connected with the main control system;
wherein the wave making test system comprises symmetrically arranged glass plates, a first bottom plate and a second bottom plate are arranged on a left side and a right side between the two opposite glass plates, and the wave making test system is isolated from the rock and soil confining pressure test system by virtue of the first bottom plate and the second bottom plate;
a telescopic motor spring is arranged at a bottom of the left side between the two glass plates,
a top end of the telescopic motor spring is connected with a wave making bottom plate,
a top end of the wave making bottom plate is connected with a wave making box, and a wave making upper plate is rotationally connected to a top end of the wave making box b virtue of a rotating shaft; and
a first water inlet is formed in a left side of an upper end of each glass plate, and a pressure sensor is vertically embedded into each glass plate.
