摘要
结合绢云母片岩工程特性,对BQ'围岩分级中的地下水修正系数进行优化,引入粘土矿物修正指标K4和软弱夹层修正指标K5,提出了基于"三重修正体系"的[BQ']分级法计算公式,并通过实践证明了该公式的合理性与可行性。
Combining with engineering properties of Pinal schist,this paper optimized the groundwater correction coefficient of BQ’ surrounding rock classification,introduction of clay minerals modified index K4,soft interlayer correction index K5,proposed the[BQ’]classification method calculation formula based on＂triple correction system＂,and through the practice proved the rationality and feasibility of the formula.
