Rock-soil geological investigation method for building construction

Abstract

The invention provides a rock-soil geological investigation method for building construction, and relates to the technical field of rock-soil geological investigation. The rock-soil geological investigation method comprises the following steps of obtaining a structure chart, classifying and refining, sampling and detecting, screening land parcels, modeling a foundation pit, detecting the foundation pit, and analyzing settlement. Sampling detection and an experimental foundation pit are combined, a soil and rock detector is used for detecting classified samples, rock geology parameters are obtained, samples with poor soil texture and poor geology are screened out to serve as first-step investigation, then land parcels with qualified soil texture and geology are selected, and experimental rock foundation pit construction is conducted; and detection hardware is installed in the rock-soil foundation pit, parameter data and images of the rock-soil foundation pit are collected, the settlement condition in the rock-soil foundation pit is analyzed according to data variables at different times, an exploration conclusion can be obtained, the conclusion represents the stability and other performance of the foundation pit in rock soil, and therefore, exploration is more accurate.

Description

technical field [0001] The invention relates to the technical field of rock and soil geological survey, in particular to a rock and soil geological survey method for building construction. Background technique [0002] With the continuous rapid development of the national economy, many modern buildings and infrastructure projects are constantly being built, and the foundation and foundation pit excavation depth of construction projects are also increasing. In the process of geotechnical engineering investigation, if the traditional method and survey means, cannot well meet the specific needs of design and construction, which will inevitably lead to certain difficulties in geotechnical engineering survey work; [0003] Geotechnical investigation of construction engineering is a basic work of engineering construction, and it is also a crucial link. This work provides an important basis and reference for the quality, safety, construction period and reasonable investment of engi...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the survey method is generally based on the analysis of rock and soil parameters, specifically: select the survey point, sample the soil layer, analyze the sample parameters, and obtain the judgment method of the rock and soil geology, and then, the above survey method, the obtained It is only the parameters of the rock and soil itself, and the most important thing for building construction is the stability of the foundation pit in the rock and soil, and this is not something that can be withdrawn from the parameters of the rock and soil itself, which leads to inaccurate surveys. Therefore, the present invention A geotechnical investigation method for building construction is proposed to solve the problems existing in the prior art
