2001—2005年长江三峡库区“五万方”“七千方”防治效果监测

长江三峡危岩体防治两大主体工程——“五万方”“七千方”锚索工程和T8—T12缝段承重阻滑键工程于1995年5月开工，分别于1997年8月、1999年8月竣工。崩滑地质灾害防治工程是风险很大的工程，工程施工对危岩体，特别是对其中局部敏感部位的影响是难以完全避免的，受扰动的危岩体适应应力...

Two main projects for the prevention and control of dangerous rock masses in the Three Gorges Area of the Yangtze River — the 50,000 m³ and 70,000 m³ anchor cable projects, and the load-bearing anti-sliding key project for the T8-T12 joint section — commenced construction in May 1995 and were completed in August 1997 and August 1999 respectively. Geological disaster prevention and control projects for collapses and landslides are high-risk undertakings. The impacts of engineering construction on dangerous rock masses, particularly their local sensitive parts, are difficult to fully avoid, and the disturbed dangerous rock masses adapt to the stress...
