Description
Technical Field
The application relates to the technical field of geological data processing, in particular to a method and equipment for identifying a strong weathering zone in the horizontal direction of a sandstone grotto.
Background
Strong weathering zone is one of the important bases for stability evaluation and protection scheme formulation of grotto and stone ancient architecture. The method is not only a basis for judging the change of the rock material property, but also a basis for determining the reinforcement method and the reinforcement depth of the grottoes and the stone ancient buildings. Therefore, the identification of the strong weathered zone in the horizontal direction of the sandstone has important practical significance and scientific value for protecting the heritage of the sandstone cultural relics.
At present, the scholars at home and abroad mostly adopt the traditional detection means to divide the strong weathering zone of the sandstone, and firstly, the rock physical and mechanical property indexes of the sandstone are utilized to divide the weathering zone, for example, longitudinal wave velocity, ultrasonic waves, ultrasonic CT, true density instrument, micro sounding, infrared thermal imaging technology, geological radar detection and other nondestructive detection technologies are utilized to detect the quality, density, porosity and various mechanical properties of the weathered sandstone. And secondly, dividing the weathering zone by using indexes for representing the mineral components and the micro-characteristics of the rock, such as X-ray diffraction (XRD), a Scanning Electron Microscope (SEM), a polarizing microscope and the like, detecting the components, the structures, the micro-morphology and other parameters of the same parts of the sandstone before and after weathering, and judging the strong weathering zone by comparing the changes of the parameters.

In sandstone weathering, not only can the change of physical and mechanical properties and the chemical composition of minerals occur, but also the generation and migration of salts are involved. Particularly in arid and semiarid regions, sandstone weathered is mainly controlled by water-salt migration, so that the region where soluble salt migration is active can be basically judged as a strong weathered region, and the region where soluble salt content is stable can be considered as a stable non-weathered region. Therefore, the content and the distribution of the soluble salt in the sandstone are used as the basis of the division of the strong weathering zone, and a new visual angle is provided for identifying the strong weathering zone in the horizontal direction of the sandstone. The identification process in the application is simple and easy to operate, and has the characteristics of economy and high accuracy.

At present, the scholars at home and abroad mostly adopt the traditional detection means to divide the sandstone strong weathering zone, on one hand, from the aspect of physical properties of materials, including quality, density, color, porosity, various mechanical properties and the like, the change of the properties of the materials before and after the weathering of the cultural relics is studied. Ultrasonic wave, soft X-ray, ultrasonic CT, true densitometer, mercury porosimeter are in measuring the aspect of crack topography, development state, porosity, density etc. of stone material, it is effectual, used extensively. The development of microscopic fractures within the rock is highly correlated with the degree of weathering. Numerous scholars evaluate the influence of the weathering process on the micro-crack expansion through the number of cracks of the sandstone cross section; the rock weathering degree is graded by adopting indexes such as CD, linear fracture density and the like combined by micro fracture and void ratio. With the deepening of the weathering degree, the physical and mechanical indexes of the weathering resistance testing device also change, and drilling resistance testing which is researched and developed by Italy and German scientists together is successfully applied to investigation and evaluation of the current preservation state of the rock-carving image of the ancient cave of Italy and the rock-carving of Dazu in Sichuan of China. In addition, the surface mechanical strength test is carried out on the sandstone surface layer by using the Richner hardness and the Schmitt hammer, the rock weathering coefficient quantitative description rock weathering degree is obtained by testing the longitudinal wave velocity of weathered rock and the longitudinal wave velocity of fresh rock, and the research and application of the rock weathering degree are further deepened by detection modes such as geological radar detection, infrared thermal imaging, high-density electrical method and the like. And secondly, dividing a strong weathering zone by utilizing indexes representing rock mineral components and micro-characteristics, such as X-ray diffraction (XRD), scanning Electron Microscopy (SEM), a polarizing microscope and the like, and judging the strong weathering zone by detecting components, structures, micro-morphology and crystal structures before and after the sandstone weathering to obtain comparison data and changing comparison parameters. Thirdly, by utilizing methods such as an X-ray fluorescence spectrometry (XRF) method and the like, the change rule of chemical components before and after rock weathering is ascertained, and more than 20 chemical weathering indexes are provided for determining the weathering depth, such as chemical alteration index CIA, pake weathering index WIP, plagioclase alteration index PIA, chemical weathering index CIW, component variation index ICV and the like, and the strong weathering zone of sandstone is judged from the angle of chemical component change.
The traditional detection methods have lower efficiency, are mainly concentrated on the research on the solid-phase apparent morphology and mineralogy of sandstone, and have certain limitations. In addition, in terms of the weathering depth determination method, grottoes and stone ancient architecture sandstones have their specificity compared with geologic bodies or conventional geological engineering. The depth of the weathering zone in the traditional geology sense is tens of centimeters, and the depth is tens of meters, and the value of the weathering zone is mainly in the range of a few centimeters to tens of centimeters on the superficial surface for grottoes and stone ancient buildings. Therefore, the conventional method for determining the strong weathering zone of the geologic body is not suitable for researching the strong weathering zone of the sandstone of the grotto and the stone ancient building.
In order to make the division of the strong weathered band more accurate, the method in this embodiment further includes:
dividing the weathered zone by using rock physical and mechanical property indexes of sandstone to obtain a first weathered zone dividing result;
dividing the weathered zone by using indexes representing rock mineral components and micro-characteristics to obtain a second weathered zone dividing result;
