Geotechnical engineering investigation method for linear project

Abstract

The invention discloses a geotechnical engineering survey method for linear engineering, which comprises the following steps: 1) dividing the geotechnical survey area into several working sections along the project direction; 2) performing horizontal orientation on the measured area of ​​each working section Drill holes to form two tunnels. The plane formed by these two tunnels is parallel to the ground. A channel is laid on the upper surface of the ground. Pipelines that can be passed through by engineering geophysical detectors and receivers along the project direction; 3) place engineering geophysical detectors in one of the pipelines, and put receivers in the other pipeline, and place the engineering geophysical detectors and receivers through the same pipe. One end moves to the other end, so as to detect and obtain the geotechnical survey data of each area; 4) The engineering geophysical prospecting instrument and the receiving instrument are interchanged into different pipelines, and multiple sets of data are measured, collected and calculated.

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...

Problems solved by technology

[0008] In short, there are three types of existing geotechnical engineering exploration methods. Among them, pit exploration and drilling are direct methods, which are in the form of "point" surveys, and the results are clear. Engineering geophysical prospecting is an indirect method, which is affected by environmental factors and the limitation of instrument measurement accuracy. , the result is roughly
