摘　　要：山地旅游景区中因块体失稳和边坡失稳造成的人员伤亡事件不断发生,严重影响着旅游景区的安全运营。为保障旅游安全,本文以浙江某山地旅游景区进出口边坡为研究背景,通过三维激光扫描仪扫描边坡岩体,结合基于坐标投影法已开发的岩质边坡工程块体稳定性评价及可视化软件(CPG程序)对岩质边坡块体稳定性进行分析,并采用FLAC^(3D)数值分析手段,对岩质边坡整体稳定性进行分析,最后利用有限元分析所提出的相应防治措施。研究结果表明,部分典型块体稳定性系数低于安全系数1.2,且受软弱夹层影响,边坡坡脚处有较大的剪应力及横向应力;钢栈桥最大拉应力区域较小,值均在1 MPa左右。在此基础上,提出清除块体、排水、锚喷、避让等多项综合措施,形成了具有山地旅游景区特色的防治对策。At mountainous tourist attractions,casualties caused by block instability and slope instability continue to occur,which seriously affects the safe operation of tourist attractions.In order to ensure tourism safety,this paper takes the import and export slope of a mountain tourist scenic spot in Zhejiang as the research background.It scans the slope rock mass with 3D laser scanner,combines the rocky slope engineering block stability evaluation and visualization software(CPG program)already developed based on coordinate projection method to analyze the rocky slope block stability.It uses the FLAC^(3D) numerical analysis method to analyze the overall stability of the rock slope,and finally uses the finite element to analyze the proposed corresponding preventive measures.The research results show that the stability coefficient of some typical blocks is lower than the safety factor of 1.2.Due to the influence of weak interlayer,there is a large shear stress and transverse stress at the foot of the slope.The maximum tensile stress area of the steel trestle is small,and the stress value is about 1 MPa.On this basis,a number of comprehensive measures such as block removal,drainage,anchor spraying and avoidance are proposed,forming a prevention and control countermeasure with the characteristics of mountainous tourist scenery.
