摘要

利用国内外常用的RMR(Rock Mass Ruting)和Q工程岩体分类体系，对小浪底工程中的地下工程进行了岩体的分类研究，并根据分类结果提出了地下工程的支护措施，估计了岩体的抗剪强度和变形模量。工程实践结果表明，分类结果是合适的，依据分类结果制定的支护方案是合适的。运行结果表明工程处于稳定状态。

Abstract

The paper focus on the classification rockmass surrounding the Xiaolangdi underground powerhouse. Two rock mass classification systems

RMR and Q

have been used to classify the rockmasses surrounding the underground powerhouse. The supporting measures are suggested based on RMR and Q classifications. The shear strengths and deformation moduli of the rockmasses have been estimated based on the rockmass classification. The monitoring result shows that the underground powerhouse is under the situation of safety.
