中文摘要：

对影响滚石的岩性、地形坡高和地质结构等因素进行现场地质调查和分析，初步确定存在潜在滚石的坡体。借助BJSD-2B型激光断面仪，选取上述坡体的4个典型剖面进行坡形测量。结合数值分析结果，确定块石A-F发生滚石的可能性较大。现场测量确定A-F块石的体积。在此基础上，利用Rocfall模拟软件对6块块石滚落的运动特征（运动距离、弹跳高度、动能和运动速度）进行预测和分析。结果表明：块石D的失稳对游客的生命安全威胁相对较小，但会直接导致7号洞洞室发生严重破坏；其余5块块石的失稳均会对游人的生命安全造成重大威胁，但不会严重影响到相应洞室的稳定。建议对上述6块块石所在坡体的关键部位及时采取工程措施进行加固。

英文摘要：

For the sutra cases of Shijing Mountain based on the investigation in site, the lithology, terrain and the geologic structure are analyzed. The potential slopes with rockfall are confirmed initially. Four typical profiles are selected on the slopes and surveyed by BJSD-2B laser profiler. With the results of the numerical simulation, the locations A-F on the profiles are confirmed as the potential rockfall sources with the bigger possibility to fall. The volumes of blocks situated at A-F are gained in site. On the basis above, the kinetic characters（run-out distances, bounce height, kinetic energy and the translational velocities ）of the six blocks are predicted and analyzed by the help of the rocfall software. The simulation results show that the rockfall of the block D threatened the life safety of the tourists less than other blocks, but it could destroy the sutra cave No.7 greatly. Oppositely, the rockfall of the other five blocks would threaten the life safety of the tourists greatly, but they wouldn＇t destroy the relevant caves. The suggestion that the key locations and blocks should be reinforced as quickly as possible is given.
