| 摘 要： | 本文应用水压致裂地应力测量法和声发射法,在山西太原引黄工程的两个钻孔中进行了地应力测量,得到了可靠的数据,为隧洞设计提供了依据。文章首先对水压致裂测量方法进行了介绍,然后给出了测量结果。并对隧洞断面的设计和岩爆问题进行了讨论。根据岩爆发生的准则指出,若隧洞走向与最大水平主应力平行,且选择适当断面,将减小岩爆发生的可能性。

| Abstract: | Both hydrofracturing method and acoustic emission method were employed for stress measurements at depth of 360m and 420m respectively in two drill holes at Taiyuan, Shanxi.The results obtained will be used in the tunnel design for the water diversion pro-ject.In this paper the two methods are first described.From the measurements, the design of the planned tunnel and the problem of rock burst are also discussed.It is shown that if the strike of the tunnel is taken to be parellel to the maximum horizontal stress and a right shape for the tunnel section is adopted, the probability of rock burst will be reduced. |
