花山谜窟景区2号、35号洞窟位于安徽省黄山市的新安江畔,其所处的地质环境条件复杂,洞窟区岩石力学的强度差异大,洞窟顶板裂隙较发育,顶板渗水较严重,加之,洞窟内部分支撑柱的间距过大,洞窟开发过程中忽略了对洞窟地质环境的保护等,引发了片状剥落、块状坠落、新生裂缝(顶板及支撑柱)三类洞窟变形失稳问题,这三类问题不仅破坏了洞窟内的地质环境,同时,也给洞窟的科学保护带来了隐患。为此,对洞窟稳定性问题产生的条件进行分析研究,并在此基础上提出了加强洞窟地质环境保护的对策。
花山謎窟景區2號、35號洞窟位于安徽省黃山市的新安江畔,其所處的地質環境條件複雜,洞窟區巖石力學的彊度差異大,洞窟頂闆裂隙較髮育,頂闆滲水較嚴重,加之,洞窟內部分支撐柱的間距過大,洞窟開髮過程中忽略瞭對洞窟地質環境的保護等,引髮瞭片狀剝落、塊狀墜落、新生裂縫(頂闆及支撐柱)三類洞窟變形失穩問題,這三類問題不僅破壞瞭洞窟內的地質環境,同時,也給洞窟的科學保護帶來瞭隱患。為此,對洞窟穩定性問題產生的條件進行分析研究,併在此基礎上提齣瞭加彊洞窟地質環境保護的對策。

The maze cave scenery of Huashan is on the bank of Xinan river in Huangshan city of Anhui, and its geologic environment condition is complication. It is apparent that there are strength difference of the rock mechanics with well developed roof crack and heavy water creep. On the other hand, the distance between the support piles is big inside caves and the geologic environment protection was neglected when cave was developed. So there are three deformation destabilization problems which including sheet scaling, block falling, and new cracks forming (in roof and support piles). The geologic environment is damaged inside caves and many hide dangers are brought on scientific protection too. On the basis of analysis these problems, the forming of cave stability condition is analyzed and researched and the protective measures are suggested in this article.
