| A Study of Stress State and Engineering Stability of Underground Houses at the Huanggou Accumulation Power Station |
| In order to detect stress state of underground houses at Huanggou accumulation power station in Heilongjiang Province, the authors made stress measurement by means of hollow inclusion gauge method. The results indicate that the maximum principal stress is nearly horizontal, trending N78°W with value of 9.6 MPa. The measurement is consistent with the present regional tectonic stress field. On the basis of stress measurement, rock mechanical testing and finite element calculation, an optimum direction of the long axis of underground houses is suggested from an overall consideration of the measured direction of maximum principal stress, enginee ring geology and construction facilities. |
