STUDY ON THE EFFECT OF HORIZONTAL JOINTS OF PERMANENT SHIP LOCK LINED WALL ON FORCING OF STRUCTURE AND ANCHORED BARS AT THE THREE GORGES PROJECT

The jointed and whole structure types of lock bay wall for the permanent ship lock of Three-Gorges project are computed and analyzed by using a method for simulation and computation of 3-D contact nonlinear structure temperature creep in the paper. The study shows that the vertical tensile stress value of strcture concrete can efficiently reduced by horizontal joints of lock bay wall, the maximum tensile stress value of anchored bars and average tensile stress value of anchored bars are increased, the stress distribution of anchored bars is more discrete, and tension stress concentration of anchored bars appears on the conjunction of horizontal and vertical joints.
