Embodiment Construction

[0019] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

[0020] Embodiment: Whether carry out foundation soil excavation with building foundation, set up calculation model such as figure 1 , figure 2 shown. in figure 1 It is only a comparison of stress distribution under extreme working conditions (the foundation depth is 0m). The stress calculation model of this embodiment is based on the use of figure 2 All working conditions can be met.

[0021] Such as figure 2 As shown, the calculation model sets the proposed building width L 1 , high H 1 , the average compressive stress of the proposed building on the base is P 1 . Without affecting the purpose of calculation, the model assumes that the foundation soil is distributed in a binary structure: the upper expansive soil layer...

Abstract

The invention relates to the technical field of geotechnical investigation and especially relates to an expansive soil calculating model and an application method on the basis of engineering boundary condition. The invention is characterized in that the calculating model comprises a to-be-built building, an expansive soil layer and a lower lying soil layer the expansive soil layer is positioned above the lower lying soil layer; the to-be-built building is set above the expansive soil layer; the calculating model uses a section as a research object and is used for evaluating the impact of the expansive soil layer on the to-be-built building; the building condition of the calculating model comprises at least the dimension of the to-be-built building, the load of the to-be-built building, the distribution width and the distribution depth of the expansive soil layer, and the distribution width and the distribution depth of the lower lying layer. The invention has following advantages: the calculating model has strong versatility and can be adapted to different conditions and has a wide application range; the calculating results are accurate and the calculating process is simple; the calculating model provides guidance for the subsequent design and construction of to-be-built building and has analysis meaning.

Description

technical field [0001] The invention relates to the technical field of geotechnical survey and design, in particular to an expansive soil calculation model based on engineering boundary conditions and an application method thereof. Background technique [0002] In recent years, the pace of national infrastructure construction has been steady, the main structure of buildings has various forms, and technical standards have become increasingly stringent. The selection of construction sites for industries such as railways, water conservancy, and civil construction gradually breaks away from traditional basic constraints, and is more restricted by government guidance, urban function positioning, and land planning. In a certain sense, the influence of engineering geological conditions on site selection has been downplayed, and the investment in basic engineering such as foundation treatment and structural design has been increased. There are different ranges of expansive soil dis...
