The Lined Wall Design And Inspects Of Three Gorges Permanent Navigation Lock

This thesis is divided into two parts: firstly, under the conditions of contact character assumption of the lined wall with the rock wall and the contact character assumption of horizontal joints of permanent ship lock lined wall, I use the calculation of the temperature stress to analyze the temperature field, the temperature stress and the anchor bar stress of the building time. Then I take the second sluice clamber as the model to calculate the temperature field, concrete stress and the anchor bar stress. And use the outcomes to calculate the ratio of reinforcement includes structure stress, intension and crack control calculation. Secondly, I use the dates of the structural monitoring to analyze in following five facets: anchor bar stress, the surface separation of the lined wall and the rock wall, the water level of the confining pressure pipe around the sluice clamber, the percolation gradient the osmometer measuered and the distortion of the lock wall. The main harvest of this thesis follows:1. In this thesis, the simulation calculation has divided into three situations: the thickness of the lined wall is 1.2m,1.5-2.1m and 2m. None of the situation has the steady temperature field. At the beginning 2 or 3 days of concret placing the heat of the hydration disappeared. 5 years later, the temperature of the lined wall accords with the outside and changes in sinusoid.2. Contact character of the lined wall with the rock walland the horizontal joints of permanent ship lock lined wall play the most important effects of all factors. Three contact situations are calculated in this thesis: absolutely contact, absolutely separate, the third one is between the two previous situations. With the combination of the analysis of the temperature stress and the practice engineering experience, this thesis takes the most disadvantageous contact situation, absolutely separate, as the calculation condition.3. The lined wall temperature stress is a stretched stress causes by the change of the annual temperature variety. The outer constrain stress arouses by the difference in temperature of the inner and outer surface of the lined wall and the inner constrain stress arouse by the non-linear distributing are small.4. The datum of the structural monitoring indicates that most of the dates are normal.
