Abstract: A method and device for preparing karst caves based on 3D printing technology. The method includes the following steps: determining size of a sample according to test requirements, constructing a 3D karst cave digital model based on three-dimensional karst cave scanning result, and carrying out 3D printing by using alloy to form primary karst cave sample; preparing rock similar material mixture according to proportioning scheme; pouring mixture into sample mold while burying karst cave model into mixture according to position of a karst cave; curing sample together with mold at room temperature until rock similar materials get hardened, removing mold, curing formed karst cave rock sample at constant temperature and constant humidity and then baking or heating same by electrifying heating wire in alloy to form rock sample with hollow karst cave; and filling hollow karst cave with different fillings to form different type of karst cave sample.

Abstract: An intelligent lithology identification system and method based on images and spectrum technology. The intelligent lithology identification system includes a rock shape analysis system, an image identification system, a sample processing system, a spectrum analysis system, and a central analysis and control system; wherein the central analysis and control system determines the final lithology of a sample according to the rock identification results from the image identification system and the analysis results from the spectrum analysis system. The technical solution further identifies the content and type of minerals by using spectrum technology, integrates and analyzes the results of spectrum analysis and image identification, and finally gives the lithology of the rock, which greatly improves the accuracy of lithology identification.

Abstract: A sandbox test system and method for a karst aquifer based on tracer-hydraulic tomography inversion, including a visual sandbox apparatus, a karst conduit, a water flow control apparatus, a horizontal well, a data acquisition apparatus, and a data processing apparatus. The visual sandbox apparatus forms a sand layer packing space. The karst conduit is buried in a sand layer. The water flow control apparatus is a constant water head storage tank. A back plate is provided with a horizontal well mounting hole and tracer adding hole. The horizontal well is mounted in each horizontal well mounting hole. A monitoring well is connected to a seepage pressure sensor or an electrical conductivity sensor. A water injection and pumping well is connected to a peristaltic pump. The electrical conductivity sensor, seepage pressure sensor, and peristaltic pump connect to the data acquisition apparatus. The data acquisition apparatus connects to the data processing apparatus.
