【摘要】 本文介绍了青藏高原昆仑山和羊八井的地应力实测结果。昆仑山的最大水平主应力量值为6.8～12.9MPa;羊八井的最大水平主应力值为3.3～10.4MPa,它们的最大主应力方向为北东和北东东向。此外,结合工程地质调查结果,还对青藏铁路昆仑山隧道和羊八井隧道群的有关问题进行了讨论,提出了一些建设性意见。更多还原

【Abstract】 Thee paper reported the result of ground stress measurements of the Kunlunshan and the Yangbajing in Qinghai-Tibet plateau.Themaximum horizontal principal stresses near the surface are 6.8～12.9MPa in Kunlunshan, and 3.3～10.4MPa in Yanbajing. Directions ofmaximum principal stresses are NE and NEE.This is agree with the result of the study of continent dynamics. Combined with engineering geo-logical condition,we discussed some related problems about the Kunlunshan tunnel and the Yangbajing tunnel of the Qinghai-Tibet railway un-der construction. We also provide some suggestion for railway building.更多还原
