This invention discloses a method for dynamically detecting the morphology of a cavity based on interlayer fracture vibrations, belonging to the field of cavity construction and monitoring technology for salt cavern gas storage. The method involves drilling and trenching to locate the cavity center and mudstone interlayer, deploying monitoring points and burying distributed monitoring optical fibers in the outer region of the cavity wall to capture the vibration wave signals of the interlayer fracture, recording the time difference and fluctuation intensity differences; analyzing the signal data of the propagation path to establish a three-dimensional coordinate system; and establishing a system of equations based on the time difference between the primary fracture vibration and the secondary vibration from the rock impact to calculate the three-dimensional coordinates of the fracture point and characteristic points of the cavity wall; then reconstructing the real-time contour of the cavity based on the layered symmetrical fracture characteristics and signal energy characteristics, and verifying it with other signals from the fracture layer and correcting the accuracy of the monitoring equipment. This method does not require interruption of the cavity construction operation, has high spatiotemporal resolution, and can accurately invert the cavity morphology, providing a basis for dynamic adjustment of the flow velocity and direction in water-soluble cavity construction, effectively reducing the risk of cavity collapse and excessive lateral dissolution.

The invention discloses a two-way reinforced concrete dense rib beam floor system structure with holes reserved in column caps and beams and a building. The two-way reinforced concrete dense rib beam floor system structure comprises frame columns, the column caps, the frame beams, secondary beams and floor slabs. The plurality of frame columns are vertically arranged on the floor; the column cap is of a columnar structure, the upper surface and the lower surface of the column cap are parallel, and the height of the column cap is set according to requirements. The column cap is arranged at the top of the frame column, the column cap and the frame column are integrally poured, the cross section of the column cap is larger than the cross section area of the frame column, and the frame column is located within the range of the column cap on the projection of the horizontal plane; the frame beams are connected between every two adjacent column caps, each secondary beam comprises a first beam body and a second beam body which are arranged in a staggered mode, and the first beam bodies and the second beam bodies are supported between the frame beams; the column caps, the frame beams and the secondary beams are arranged at the same height. By reducing the span of the frame beam, the height of the frame beam is reduced or the bearing capacity of the frame beam is improved, so that the problems that the construction cost of earthwork in an excavation area is high, the economical efficiency and the applicability of a conventional structure are poor, and the contradiction exists between the strong load capacity and the clear height increase are effectively solved.
