500米口径球面射电望远镜台址岩堆稳定性分析
摘要
500米口径球面射电望远镜(Fivehundred meters Aperture Spherical Telescope,简称FAST)采用我国科学家独创的设计和我国贵州南部喀斯特洼地独特的地形条件,是世界上最大单口径射电天文望远镜。FAST台址区工程地质条件复杂,面临的岩土工程问题也具有一定的独立性、复杂性和特殊性。FAST台址岩堆中多为大块石,有的直径甚至超过10m,其局部物理力学性能和岩体密切相关,不能完全用岩石或者土体来解释,这就决定了块石(岩堆)的稳定性评价标准与碎石土有很大区别。对FAST台址区所存在的岩堆的稳定性问题进行系统的评价论述,为今后相似场地的块石(岩堆)岩土工程稳定性问题提供相应的理论依据和经验。
