摘要
岩体抗剪强度参数是石窟寺危岩整治工程中不可或缺的数据,因石窟区文物密集、工程规模小,不便取样,致使项目中使用的参数多以定性、经验值为准,可靠度低,文章引入Hoke-Brown准则以期解决该问题。首先阐释了HB准则的理论基础、求解过程,并对云冈石窟危岩稳定性进行分析,讲明使用过程。推广应用该方法,有利于行业规范岩体抗剪强度参数确定过程。
Rock shear strength parameters are key data in the dangerous rock mass treatment project of Grottoes.Due to the dense cultural relics,small scale of the project and inconvenient sampling,the parameters used in the project are mostly based on qualitative and empirical values with low reliability.This paper introduces the Hoke-Brown criterion to solve this problem.In this paper,the theoretical basis and solution process of HB criterion are explained firstly.Finally,the stability of a dangerous rock mass in Yungang Grottoes is analyzed and the application process is explained.The popularization and application of this method is beneficial to standardize the determination process of rock mass shear strength parameters.
