| 为研究广西大石围天坑群白洞天坑建设巨型垂直电梯的适宜性,本文在资料收集基础上,采用综合勘察手段,探究白洞天坑的发育特征、形成原因、发展趋势,以及危岩和边坡稳定等问题。研究表明,天坑发育与岩性、构造、水等因素密切相关,白洞天坑发育比较成熟,处于平稳期,危岩安全和边坡稳定是可以防治的,初步判断白洞天坑电梯建设具有一定的可行性。同时应对基础可利用型式、局部危岩主被动防护、减少施工和运营对生态系统的扰动等开展进一步的相关论证工作。本文研究可为类似工程提供参考。 |
| 英文摘要: |
| In order to study the suitability of constructing giant vertical elevator in Baidong Tiankeng of Dashiwei Tiankeng group in Guangxi, On the basis of data collection, in this paper, comprehensive survey methods are adopted. The development characteristics, formation causes, development trend, dangerous rock and slope stability of Baidong Tiankeng are explored. The study shows that the development of Tiankeng is closely related to lithology, structure and water etc. Baidong Tiankeng is relatively mature and in a stable period. The dangerous rock safety and slope stability can be prevented and controlled. It is preliminarily judged that the elevator construction in Baidong Tiankeng is feasible. At the same time, we should carry on the further related demonstration work to the foundation available type, the local dangerous rock active and passive protection, the reduction construction and the operation disturbance to the ecosystem. This paper can provide reference for similar projects. |
