安徽花山古代大型地下洞室群工程地质条件与变形破坏规律研究
|
摘要
本文从工程地质条件和岩石力学两方面对古洞室群围岩的变形破坏规律,特别是支顶岩柱拉裂和剪裂破坏及顶板掉块等进行了研究,对洞室群的稳定性做出了初步评价。在此基础上,提出了以防止地表水沿裂隙入渗和建立一个高效监测系统为主要手段的建议。
Huashan grotto is a large ancient underground cavern of a history of 1700 years in Anhui province.Partial instability has appeared since it was open for tourists in 2000.In order to protectively exploit the rare relict of the underground quarry group in the ancient city of Huizhou,the deformations and failures of the surrounding rocks are examined from the viewpoints of engineering geological conditions and rock mechanics.This paper places its emphasis on the analysis of the tensional and shear fissures on the pillar supporting the roof,and the block collapse from the roof.Moreover,assessment of stability is carried out preliminarily.Based on the above research and assessment,prevention of the groundwater penetrating into the cave from fissures and joints can responsibly control the failure of the surrounding rock,and an effective monitoring system is needed to be set up.
