Formation mechanisms and prevention methods of surrounding rockfall in Shuiyun Cave of Changyu Dongtian
摘要
Abstract
Changyu Dongtian,as a large-scale ancient underground chamber group left over from quarrying,boasts abundant tourism resources and significant scientific value,with its surrounding rock stability drawing considerable attention from the academic community.However,the destructive phenomena during the tourism development process pose a threat to the safety of the heritage,and Shuiyun Cave,in particular,harbors numer-ous hazards of falling rocks from the surrounding rock.Taking Shuiyun Cave as the research object,a geological model was constructed through field surveys,drone oblique photography,and three-dimensional laser scanning fusion technology.Software such as Geomagic,Hypermesh,and Flac3D were employed to conduct numerical simulations of the stability of the chamber's surrounding rock,exploring the formation mechanism of falling rocks.The results indicate that the overall stability of Shuiyun Cave's surrounding rock is good,but the devel-opment and mutual cutting of structural planes within the cave lead to stress concentration in the roof and side-wall areas of the chamber.Under long-term weathering,the fragmentation of local rock masses is an important reason for the continuous occurrence of falling rock problems.Consequently,it is proposed to regularly inspect and clean potential falling rock areas in the chamber,and to set up an classical-style corridor at the chamber's exit and optimize tourism development routes to address potential falling rock issues.The research results not only provide a decision-making basis for the long-term stability protection and tourism development of Shuiyun Cave,but also offer a reference example for solving similar geological problems in modern underground engi-neering construction.关键词
