摘要
目前我国水利水电深埋长隧洞工程原始地应力测试深度多在500 m以内,更深的地应力分布主要靠经验理论与公式推测,存在许多问题。提出推测深部地应力应注意的问题和推测方法。
At present,the initial ground stress testing depth for deep buried and long-distance tunnel of Chinese water resources and hydropower projects is usually within 500m.Deeper ground stress is mainly predicted on the basis of experience and formula,therefore,there exists many problems.This test lists the problems and prediction methods for deep ground stress testing.
