Aiming at the defect that the traditional geological compass is easily disturbed by the magnetic field and cannot measure the occurrence of the structural surface when the trace is exposed, the present invention provides a method for measuring the occurrence of the rock mass structural surface based on dual-image analysis, which is especially suitable for In the underground excavation project, the occurrence measurement of the structural surface exposed by the trace is to first solve the three-dimensional coordinates of multiple anchor points on the trace through dual images. Since the surrounding rock is obviously uneven after blasting, the minimum two The equation of the plane where the trace is located is determined by the multiplication plane fitting method, and then the occurrence of the structural plane is interpreted

The invention discloses a rock mass structural plane occurrence measurement method based on double-image analysis, which comprises the following steps: arranging control points, and respectively shooting a surrounding rock image from left and right angles; estimating interior orientation elements and exterior orientation elements when the two images are shot; carrying out error analysis, and judging whether the image analysis precision meets the requirement or not; arranging a plurality of anchor points along each structural plane trace in the left image; searching the position of the anchor point in the corresponding right image; solving the three-dimensional coordinates of the anchor points by using a collinearity equation; determining a plane equation of the structural plane; and interpreting the tendency and the dip angle of the structural plane according to the plane equation. The method can be used for measuring the situation that the exposed area of the structural surface is very small, only the trace is exposed, and a geological compass cannot be directly used for measurement, is not interfered by a magnetic field, and has the advantages of being safe, accurate and rapid in measurement.
Description
technical field [0001] The invention relates to the technical field of rock mass measurement, in particular to a method for measuring the occurrence of a rock mass structure plane based on double image analysis. Background technique [0002] Rock mass structural plane is an important content in rock mass engineering research. The three elements of the structural plane include: strike, inclination and dip. At present, the geological compass is used as a conventional method for measuring the occurrence of rock mass structure surface, but it is easily interfered by magnetic field, resulting in inaccurate measurement results, and there is a great safety risk in close contact with the rock surface. In addition, the geological compass is suitable for the structure surface with a large exposed area, but in some underground projects such as traffic tunnels or underground mine roadway excavation, it is common that the exposed area of the structure surface is very small, only showi...
