摘要:
岩溶隧道围岩质量评价是困扰岩溶隧道支护结构设计的重难点问题之一，本文以BQ值围岩分级方法为基础，分析研究了岩溶对岩石坚硬程度、岩体完整程度两项围岩质量指标的影响规律及特征，并以此构建了基于BQ值修正的岩溶围岩分级方法，通过工程实例验证，检验了分级方法的合理性。研究成果对岩溶隧道围岩质量评价及分级具有一定的参考和借鉴价值。
Abstract:
The quality evaluation of surrounding rock of karst tunnel is one of the most difficult problems in the design of supporting structure of karst tunnel. Based on BQ value-based surrounding rock classification method, this paper analyzes and studies the influence law and characteristics of karst on rock hardness and rock integrity, and constructs a karst surrounding rock classification method based on BQ value correction. The rationality of the classification method is verified by engineering examples. The research results have certain reference value for the quality evaluation and classification of surrounding rock of karst tunnel.
