Test device and test method for excavation model of foundation pit containing karst cave
The invention discloses a test device and a test method for an excavation model of a foundation pit containing a karst cave. The test device comprises a test model box, horizontal supporting devices, displacement measuring devices, a karst cave generating device and a data acquisition device. Similar materials are filled in the test model box in a layered mode, and in the process of filling the similar materials, the karst cave generating device, retaining walls and the displacement measuring devices are sequentially installed. The karst cave generating device forms the karst cave, then the similar materials between every two adjacent retaining walls are excavated to form the foundation pit, and the horizontal supporting devices are installed between every two adjacent retaining walls. The displacement measuring devices measure the displacement of the retaining walls, and the data acquisition device acquires the settlement of the similar materials, the side pressure of the retaining walls and the axial force of the horizontal supporting devices. According to the test device and the test method for the excavation model of the foundation pit containing the karst cave, the excavation model test of the foundation pit containing the karst cave is realized through the cooperation of all the devices, and the accuracy of a test result can be guaranteed.
本发明公开了一种含溶洞基坑开挖模型试验装置及试验方法，包括试验模型箱、水平支撑装置、位移测量装置、溶洞生成装置及数据采集装置。在试验模型箱内分层填筑相似材料，且填筑所述相似材料的过程中，依次安装所述溶洞生成装置、挡土墙及位移测量装置。使所述溶洞生成装置形成溶洞，然后开挖相邻两个所述挡土墙之间的相似材料形成基坑，在相邻两个所述挡土墙之间安装水平支撑装置。所述位移测量装置测量所述挡土墙的位移，数据采集装置采集相似材料的沉降，采集所述挡土墙的侧压力，采集所述水平支撑装置的轴力。上述含溶洞基坑开挖模型试验装置及试验方法，通过各装置间的配合实现含溶洞基坑的开挖模型试验，可以保证试验结果的准确性。
