| Abstract: | In this article,stress anslysis are made on the curtain's in-tensity by means of photoelastic tests.Thus main design parameters are obtained such as the altitude of the water head in a shifting sand layer, the depth of earth filled on the upper part of the curtain, and the thickness of the curtain and their influence on the curtain in the inclined shaft and their law is obrained as well.
A simple formula for calculating intensity is also suggested for the reference in the design of the curtain intensity in an inclined shaft including similar engeering. |
