ON MESO DAMAGE BEHAVIOUR AND LONG TERM STABILITY OF HIGH SLOPE ROCK OF THE THREE GORGES SHIPLOCKS
三峡船闸高边坡岩体的细观损伤 及长期稳定性研究

With a scanning electron microscope, the authors carried out a series of tests on the amphibole plagioclase granite, taken from the weakly weathered zone of the high slope of the Three Gorges shiplocks, and investigated the meso time dependent damage behaviour of the rock. Then, on the basis of the meso damage theory for brittle elastic rock mass, which was established by the authors, this paper analysed the influences of meso time dependent damage of the rock on the stability of the shiplocks slope. It is shown that the long term stability of the slope will be very good if only from the point of view of the creep rupture time of the rock material.
