摘要
本文通过云台山隧道膨胀性围岩岩性的研究，确认其围岩含有伊利石、绿泥石等膨胀性矿物，具有一定的膨胀性，属于弱膨胀岩。提出了膨胀岩的快速测定方法。为在膨胀岩地层中进行新奥法的隧道施工，提供了合理的设计参数。
On the basis of the investigations on the properties of the expansive rocks inYun Taishan Tunnel,it is confirmed that they consist of expansive clay minerals such as il-lite,chlorite etc. and are only slightly expansive. They are classified as weakish expansiverocks,Quick field methods of identifying the expansive properties of rocks are suggested inthis paper,Also,appropriate design parameters are furnished for tunnel construction by NewAustrian Method in expansive rock strata.
