Application of inclined bracing inner support ring in high and steep dangerous rock treatment engineering
-
摘要: 本文研究的危岩体处于一座小型古亭下方的地基部位，在保护古建的前提下，治理危岩体的难度明显增大。由于危岩体位置高陡，其下方已形成倒三棱锥形崩塌岩腔，并且危岩体所在岩石陡壁坡脚处为石景山古建山体特色景观公园的景观小路，以上因素对危岩体的治理提出了严峻挑战。经多方案比选，最终采取了在危岩体下方采用工字钢斜撑内支撑环治理措施。经实施及竣工后观察，该措施对小型古亭地基的保护及治理效果良好。本研究对于类似特殊条件下的危岩治理工程具有一定借鉴作用。Abstract: The dangerous rockmass studied in this paper is located at the foundation site under a small ancient pavilion,under the premise of protecting ancient buildings,the difficulty of controlling dangerous rockmass increases obviously.Because of the high and steep location of the dangerous rockmass, and a inverted pyramidal collapse cave chamber has been formed below it,moreover, there is a landscape path of the characteristic landscape park of Shijingshan ancient construction mountain body located at the foot of the steep slope of the dangerous rockmass, severe challenges to the treatment of dangerous rockmass are posed. After comparing and selecting several schemes, the measure of I-steel inclined bracing inner support ring under the dangerous rockmass is taken. As the observation during the construction and upon completion, it has a good effect on the protection and treatment of small ancient pavilion foundation. This study can be used as a reference for dangerous rock treatment projects under similar special conditions.
