| Abstract: | According to the requirements of construction speed and high quality for the Three Gorges shiplockt,he key technologies such as the drilling technology of the high accuracy cable holes,the key technology of the stressing and locking,the grouting technology of the two ended cables,are studied during the anchorage construction process;and the research results are applied in the anchorage engineering of the Three Gorges Project.In addition,the reinforcement effects for the two ended cables are studied by field tests.The results show that the compression zones are formed around the two-ended cables with radius of 2 meters and depth of 8 meters and the mechanical properties of the surrounding rock mass are effectively improved. |
