Embodiment 2

[0025] The polymorphic cave filling simulation method includes the following steps:

[0026] A. Establish a karst cave model that can be deformed arbitrarily, and set the relevant filler injection port and bottom water port on the karst cave model, and then connect the karst cave pouring port metering device and the bottom port metering device;

[0027] B. Arrange the simulation model of the karst cave, set up a pressure monitoring system and an internal shape monitoring system in the karst cave simulation model, and place pressure sensors and displacement sensors at the relevant inflection points and pressure points of the karst cave. The pressure point can be the location where the stress is concentrated in the cave, and these pressure sensors are connected to the PLC control device; in the specific operation, the inflection point and the pressure point can also be set in the same position, which is convenient for control and placement;

[0028] C. Establish simulation softwar...

Abstract

The invention discloses a deformable cave filling automatic simulation system. The deformable cave filling automatic simulation system uses a single cave model unit to simulate caves in different shapes, can simulate a practical cave through measurement, analysis, statistics and standard curing, can synthesize cave simulation of different shapes, can improve accuracy of the cave in an practical operation, can properly save filling energy, can monitor stress conditions inside the cave in real time and has strong controllability. The invention also discloses a multi-form cave filling simulationmethod. The multi-form cave filling simulation method adopts multi-form deformable cave units to automatically simulate a cave form, analyzes simulation numerical values as standard parameters and transmits the standard parameters into a practical cave filling control system. Data standards are embedded in a PLC control device for practical cave filling. The deformable cave filling automatic simulation system and the multi-form filling simulation method are easy to control filling of the cave, improve filling efficiency, simulate different data standards according to a specific geologic condition of the cave and satisfy cave filling of different geologic conditions.

Description

technical field [0001] The invention relates to the technical field of karst cave simulation, in particular to a deformable karst cave filling automatic simulation system. Background technique [0002] At present, in coastal areas, the underground is dominated by sandy soil and silt topsoil. In these underground soil environments, there are often unfavorable geology such as multi-layer karst caves and beaded karst caves (including soil caves, etc.). If the caves are not filled and pre-filled Treatment will cause local slurry leakage, faults, and necking of the bored piles, and the bearing capacity of the whole pile will be lost. Therefore, the design of a hole filling pretreatment construction method has been put on the research agenda. [0003] Karst caves are formed by soluble rock under the long-term action of high water head. There are mainly two types: non-filled and filled. The anti-seepage treatment is an important part of ensuring the safe operation of civil engineer...
