Abstract In this paper，a new system of rock suitability classification named QHLW is introduced to evaluate the suitability of the host rock for high-level radioactive waste(HLW) disposal at different scales. The system is developed on the basis of Q-system，and considers both the long-term safety and constructability requirements of the host rock for disposal. Some additional parameters，including the fracture zone distribution，groundwater chemistry and thermal effect are also taken into account in light of their significant influence on the long-term safety of HLW disposal. In the QHLW system，the suitability of host rock is classified into three classes at the repository and tunnel scales. The suitability of nine potential sites of underground research laboratory(URL) for HLW disposal located in Beishan，Xinjiang and Inner Mongolia regions are evaluated with this classification system. The Xinchang site in Beishan region is classified as the most suitable URL site according to the results of analysis.

Key words： rock mechanics high-level radioactive waste disposal rock suitability classification site selection of underground research laboratory Xinchang site
