A NOTE ON THE STRESSES OF THE MIDDLE GATE BAY OF 3-GORGE-LOCK

On the basis of geological measurement data and criteria, this paper s tudies the stress distribution in a horizontal section of the middle g ate bay of Three Gorge Lock by the photoelastic experimental method, w ith the middle gate bay and the rock foundation jointly subjected to l oad under the action of the thrust of the gate. The results obtained a re compared with those calculated using the finite-element method. Thi s article also estimates the three-dimensional stress distribution in the lock and identifies the danger region, which is of reference value for the design of the three Gorge Lock.
