| 摘 要： | 在青藏高原东北缘首次采用水压致裂法进行了地应力测量,结果显示：在测量深度域内,青藏高原东北缘三个主应力之间的关系表现为σＨｍａｘ〉σＨｍｉｎ〉σｖ,水平主应力占主导地位,现今地壳应力场的主压应力方向为ＮＥ－ＮＥＥ,测量结果与地质事实较吻合。

| Abstract: | Measurement of crustal stress by hydrofracturing was first made in northeastern Qingzang plateau.As a result we have a stress state of σHmax > σHmin > σV with the horizontal principal stress trending NE-ENE which agrees with the regional structures. |
