Test device for analyzing influence of karst cave on bearing capacity of pile foundation
The invention provides a test device for analyzing the influence of a karst cave on the bearing capacity of a pile foundation. The test device for analyzing the influence of the karst cave on the bearing capacity of the pile foundation comprises a base, two stand columns, a counter-force beam, a model box, and four pieces of angle steel; the two stand columns are fixedly mounted at the top of the base; the counter-force beam is fixedly installed on the outer walls of the sides, close to each other, of the two stand columns; the model box is fixedly mounted at the top of the base; the four pieces of angle steel are all fixedly installed on the outer wall of the model box; and the four pieces of angle steel are all fixedly connected with the base. The test device for analyzing the influence of the karst cave on the pile foundation bearing capacity has the advantages that the conditions of existence of the karst cave, different sizes, different forms, different top plate thicknesses and the like can be simulated, and the development rule of a karst cave surrounding rock plastic zone in the pile foundation loading process can be visually analyzed through an image shooting technology and post-processing software.
本发明提供一种分析溶洞对桩基承载力影响的试验装置。所述分析溶洞对桩基承载力影响的试验装置包括底座；两个立柱，两个所述立柱均固定安装在所述底座的顶部；反力梁，所述反力梁固定安装在两个所述立柱相互靠近的一侧外壁上；模型箱，所述模型箱固定安装在所述底座的顶部；四个角钢，四个所述角钢均固定安装在所述模型箱的外壁上，且四个所述角钢均与所述底座固定连接。本发明提供的分析溶洞对桩基承载力影响的试验装置具有可模拟溶洞的存在与否、不同大小、不同形态以及不同的顶板厚度等条件，并通过图像拍摄技术和后期处理软件可以直观分析桩基加载过程中溶洞围岩塑性区的发展规律的优点。
