| 摘 要： | 本文根据孔壁应力解除法获得的量测应变,提出了采用最优化方法直接确定岩体的泊松比和原始地应力。实例表明,这样获得的原始地应力更符合实际——对应最小的量测残差。

| Abstract: | This paper proposes that Poisson's ratio of rock mass and in-situ stress are directly determined using optimization method according to measured strains obtained from bore hole stress relief process. An example shows that the rock stresses obtained in-situ are more conformable to reality-corresponding to the minimum measuring residual error. |

| Keywords: | stress relief method optimization algorithms least square methods strain measurements modulus of elasticity residual error |
