    世界地质公园方山两宜亭景点落石灾害成因及其防治对策研究

    STUDY ON THE CAUSE OF ROCKFALL DISASTER AND ITS PREVENTION IN LIANGYI PAVILION SCENIC SPOT OF THE WORLD GEOPARK FANGSHAN

    • 摘要: 浙江省温岭市大溪镇的世界地质公园方山景区位于早白垩世磨石山群九里坪组的火山岩地层上。方山所具有的火山岩台地地貌景观的形成与构成方山台地的较坚硬且不易风化的流纹岩有关。据现场考察,方山景区的岩体具有层状结构,工程地质条件评价为良,但与游路相关的高陡反坡却存在着较多的落石,并在台风来临时还可能发生水带泥石落下的问题。它们在某些游客出现的部位有可能形成地质灾害的严重隐患。例如方山景区两宜亭景点就曾在2013年台风来临的季节发生了一次两宜亭被从上述高陡反坡顶部水冲下来的泥石砸坏。此外,作者还在两宜亭景点发现了散落在地面上的大量落石。显然,两宜亭景点存在严重威胁旅游安全的地质灾害隐患问题。在两宜亭景点地质灾害的防治方面,作者提出了基于工程地质学与旅游规划学相结合所形成的山地旅游规划工程地质方法来调整景区的游路,以达到既确保旅游安全又可维护方山景区原状的目的。

       

      Abstract: The world geopark Fangshan scenic spot in Daxi town, Wenling city, Zhejiang province is located on the volcanic strata of Jiuliping formation, Moshishan group, early cretaceous. The formation of volcanic platform landscape in Fangshan is related to the hard rhyolite which is not easy to be weathered. According to field investigation, the rock mass in Fangshan scenic area has layered structure, and the engineering geological conditions are evaluated as good. However, there are many rockfalls in the high and steep reverse slope near the tour road, and mud and stone falling in the water zone may occur when the typhoon comes. Therefore, a serious geological hazard may be formed in some places where tourists appear. For example, in the typhoon season of 2013, Liangyi pavilion in Fangshan scenic area was damaged by mud and stones washed down from the top of the above-mentioned high and steep slope. In addition, a large number of falling rocks scattered on the ground in Liangyi Pavilion scenic spot was found. Tourism safety is seriously threatened by geological hazards in Liangyi Pavilion scenic spot. In terms of the prevention and control of geological disasters in Liangyi Pavilion, the engineering geological method of mountain tourism planning based on the combination of engineering geology and tourism was put forward to adjust the route of scenic spots, so as to ensure the safety of tourism and maintain the original state of Fangshan scenic area.
