Rapid geotechnical engineering investigation method

Abstract

The invention discloses a quick survey method for geotechnical engineering, which comprises the following steps: 1) dividing the geotechnical survey area into several circular work areas in the engineering area; 2) carrying out circular orientation in the measured area of ​​each work area Boreholes, including the outer ring and the inner ring, are arranged in the formed annular channel for the engineering geophysical detector and the receiver to pass through; 3) the engineering geophysical detector is placed in one of the annular pipes, and the other annular pipe Put the receiving instrument in the pipe, and make the engineering geophysical prospecting instrument and the receiving instrument perform circular motion with the same angular velocity in the pipeline, so as to detect and obtain the geotechnical survey data in the area. After completing step 3), exchange the engineering geophysical detector and receiver, and repeat the above step 3), so as to detect and obtain the geotechnical survey data in the area. After completing the geotechnical survey of the engineering geophysical instrument in the pipeline in the measured area, replace other geophysical instruments and receivers, and repeat step 3) to detect and obtain geotechnical survey data in the area.

Description

technical field [0001] The invention relates to the technical field of geotechnical survey, and more specifically, relates to a quick geotechnical survey method. Background technique [0002] Any civil engineering is closely related to rock and soil, they directly contact and interact with the rock and soil medium. Therefore, it is an important prerequisite for engineering design and construction to fully understand and understand the distribution characteristics of rock and soil mass and engineering properties. Exploration is the main means to reveal the spatial distribution of rock and soil (including the distribution of groundwater closely related to rock and soil) and its changes. [0003] The forms of various civil engineering foundations are different, some are in the shape of "points" and some are in the shape of "lines". In a typical building such as a frame structure, the structural columns disperse the gravity of the house to the foundation at a relatively indepe...
