Device and method for testing underwater shock resistance bearing capacity of rock-fill dam panel

Abstract

The invention discloses a device and a method for testing the underwater impact resistance bearing capacity of a rock-fill dam panel, and belongs to the field of dam safety monitoring. The water tank comprises a water tank body, a rock-fill dam concrete panel, a first fixing steel column, a second fixing steel column, a first shear flange, a second shear flange, a water inlet, a heating opening, a soil body, a distributed optical fiber vibration sensor and a distributed optical fiber temperature sensor. The air pressure jetting device comprises a fixing frame, a hollow steel pipe, a tail branch air pipe, a middle branch air pipe, an end branch air pipe and a multi-stage air blowing acceleration device. The multi-stage air blowing acceleration device comprises a main air hole airtight valve, a main air pump pipe, a branch air hole airtight valve, a branch air pump pipe and an impact body. The device has the capability of testing the underwater impact resistance bearing capacity of the rock-fill dam panel, and is simple to operate.
