1983年10月10～15日在澳大利亚墨尔本召开的第五届国际岩石力学大会上,有近40％。的论文涉及地下工程,说明近年来由于世界性的能源紧张,各国都已注意到地下空间的开发和利用。为此,地下洞室的围岩稳定,成为岩石力学研究的重点。新奥法在国际上的普遍使用,成功地修建了宽达33.4米的西德瓦尔德克抽水蓄能Ⅱ级地下厂房、闻名世界的长达23.3公里的日本青函海底隧洞,盐岩中开挖了跨度达40米的永久性地下洞室等。这些地下工程,在开挖和营运期间,是不允许发生显著变形和破坏的。岩体稳定性的判断,就是要在地下工程开挖之前和在开挖过程中,在工程地质基础上,针对拟建工程部位岩体的工程围岩稳定性作出是否稳定的判断。
October 10-15, 1983 held in Melbourne, Australia, the Fifth International Rock Mechanics Conference, nearly 40%. Of the papers on underground engineering, indicating that in recent years due to the worldwide energy shortage, all countries have noticed the development and utilization of underground space. For this reason, the surrounding rock of underground caverns is stable and becomes the focus of rock mechanics research. New Austrian law widely used in the international community, successfully built up 33.4 meters wide West Germany Waldk Pumped Storage Ⅱ level underground powerhouse, the world’s 23.3 kilometers of Japan’s Qinghai sea tunnel, salt rock excavation A permanent underground caverns spanning 40 meters. These underground works are not allowed to undergo significant deformation and damage during excavation and operation. The judgment of the stability of the rock mass is to make a judgment as to whether the stability of the surrounding rock of the rock mass of the proposed project site is stable before excavation of the underground project and during the excavation process on the basis of the engineering geology.
