Embodiment

[0046](1) With the method of the present invention, in Huaxi District, Guiyang City, Guizhou Province, the underground hole (crack) gap is selected to be the underground hole (crack) of limestone in Huaxi District, Guiyang City, Guizhou Province, and the underground hole (crack) gap morphology and soil sample collection thereof are carried out.

[0047] (2) With the method of the present invention, investigate and sample the typical vertical sections newly excavated for development and construction projects in karst areas on both sides along the highway in the research area.

[0048] (3) After selecting the excavated section, use the statistical window method of geological survey to select 3 underground hole (crack) sample squares on the section. m rectangle. When collecting the morphological characteristics of underground pores (cracks), use a geological compass to measure the occurrence and inclination angle of the bedrock of underground pores (cracks), and use a tape measur...

Abstract

The invention discloses a method for collecting information of underground pores and cracks and soil of karst. The method comprises the steps of arranging and selecting of sample points, setting of the sizes and the quantity of quadrats, an underground pores (cracks) morphological characteristics collection method and indexes, a soil sample collection method, an underground pores (cracks) soil collection method and an underground pores (cracks) soil sample collection order. Underground pores (cracks) morphological characteristics and soil samples are collected by using tools, such as a geologic compass, a leveling rod, a 5m tape and a cutting ring which are low in cost and simple in operation. The collection method has controllability and operability, and has the advantages of being comprehensive, reliable and high in practical application value; meanwhile, the problem that asymmetric collection of the underground pores (cracks) morphological characteristics of the karst and the soil samples at present can be solved. The method can play an important promoting role in research of water and soil losses of karst regions and the soil occurrence characteristics of the underground pores (cracks).

Description

technical field [0001] The invention belongs to the fields of soil and water conservation and soil science, and in particular relates to a method for collecting underground pores, fissures and soil information in karst areas, which is specially used for the morphological characteristics of underground pores (cracks) and the collection of soil samples in karst areas. Background technique [0002] my country is the country with the most widely distributed karst area in the world. Even if the buried karst is not included, the karst area developed only by the outcropping of carbonate rocks reaches 1.3 million km 2 , of which the surface karst exposed area in the southwestern region centered on Guizhou reaches 510,000 km 2 , is the most intensively developed and most concentrated area of ​​karst in the world, and is a typical area with fragile ecological environment. Under the action of dissolution, these carbonate rocks are very easy to form unique karst geological environments...
