超深竖井工程围岩分级探讨

结合超深竖井工程围岩分级过程中遇到的问题，尤其是深部高地应力、高地温等复杂条件对稳定性的影响，根据工程实际资料对这些问题进行了分析和探讨，对分级方法中的定量指标岩体完整性指数Kv和岩石饱和单轴抗压强度进行了高地应力、高地温条件下的修正，并通过典型工程实例验证了该修正方法的实用性。

Discussion on Rock Mass Classification of Ultra Deep Shaft Engineering

There are some questions in the engineering rock mass classification of ultra deep shaft,which particularly include the depth high ground-stress,high geotemperature and so on.According to the actual information,this article discusses these above questions,and amends the integrity index Kv and single axle compressive strength under the condition of high ground-stress and high geotemperature.It confirms the usability of this method through the typical project example.
