Embodiment Construction

[0047] Unless defined, the technical terms used in the following examples have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0048] Taking Tianjin Binhai New Area as an example, the implementation of this method in specific projects is introduced.

[0049] 1. Establishment of geotechnical engineering survey drilling database in Binhai New Area

[0050]The database uses the ACCESS database as the data platform, and selects the basic data items for storage, mainly including: project information data, drilling attribute data, stratum information data, geotechnical test data and in-situ test data. Table 1 shows the standard stratigraphic division data content and data volume of Binhai New Area.

Abstract

The invention provides a foundation soil standard soil layer sequence division method, which is provided on the basis of summarizing the existing geotechnical engineering investigation work experience and combining the engineering properties of soil on the basis of geological times and cause marks. According to the method, the problems that the current domestic and overseas foundation soil standard soil layer sequence division precision is not enough, lithologic layer codes are repeated, geological data are difficult to store, and a rock-soil BIM model and a geological and geographic information system are difficult to establish are solved. While the requirement of geotechnical engineering investigation data base construction is met, a foundation is laid for industry standardization, informatization and smart city construction.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, in particular to a method for dividing the standard soil layer sequence of foundation soil. Background technique [0002] The standard sequence division of foundation soil is the basis for geological data storage, and is an important basis for the construction of management systems such as geotechnical BIM models and geological and geographic information. In order to improve the level of urban management services and realize urban smart management, the standard sequence of foundation soil Division is necessary. But at present, there are different opinions and schemes on the stratigraphic layer division of foundation soil in China. Some units use the traditional Quaternary research method combined with modern technology to divide the Quaternary strata on the basis of fully considering the stratum engineering characteristics and field characteristics, but most of them do not carry out stand...
