| 摘 要： | 通过5组岩石声发射Kaiser效应地应力的测试,查明了通渝深埋特长公路隧道工程岩体内地应力的总体状态为潜在走滑型,隧道中部测得的地应力量级普遍较高,实测最大主应力σ1最高达33.04MPa,因而施工过程中应密切关注其高地应力与岩爆问题.

| Abstract: | Through geostress measurement by Kaiser effect methodi,t is found out that the general space stress state of rockmass in deeply-lying and especially long Tongyu highway tunnel belongs to the potential strike-slip type.The measured geostresses in the middle part of the tunnel are generally very large with the σ1 major principal stress of 33.04 MPa.So during the construction process,the problems of high geostress and rockburst have to be taken into account. |
