摘要

摘要: 本文运用水压致裂地应力测量方法,对我国某地下油库预可行性研究工程场区两个钻孔进行了地应力测量。测量结果表明:最大和最小水平主应力(S_H,S_h)都远大于对应深度处的垂向应力(S_v),三向主应力的关系为:S_H > S_h > S_v,应力大小在该深度范围属中等偏大级别;工程场区最大水平主应力方向近EW方向,与测点外围确定的区域最大水平主应力总体方向较为一致;建议未来地下硐库长轴按近EW分布,地应力状态、岩体结构构造、岩石强度等基本保证了其岩体稳定性。

Abstract: Hydrofracturing in situ stress measurements were used to determine in situ stress states of two drill holes for the pre-feasibility study of an underground reservoir at an engineering site in China.Both the maximum and minimum horizontal principal stresses(S_H and S_h) are by far greater than the vertical stress(S_v) at the same depth,and the SH and Sh are higher than the normal stress state at the depth range,with a relation of S_H > S_h > S_v.The maximum horizontal principal stress direction is nearly(E-W),which is in accord with the general direction of the regional maximum horizontal principal stress determined by measuring points in surrounding areas.The authors suggest that the long axis of the underground reservoir should be oriented in a nearly E-W direction in the future,and the in situ stress state,rock mass structure and rock strength will in the main ensure the rock mass stability.
