Problems solved by technology

However, due to poor consideration by designers at the design stage, excavation infrastructure may overturn under the action of natural external forces (such as wind force) and the gravity of power lines and power infrastructure itself, resulting in damage to power infrastructure and interruption of power supply
[0003] Therefore, in the engineering design of transmission lines, there is an urgent need for a method to detect the stability of the excavated foundation, so as to avoid the failure of the excavated foundation to overturn during use due to the unreasonable design of the designer, resulting in damage to the power infrastructure and interruption of power supply.

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] An embodiment of the present invention provides a method for detecting the stability of an excavated foundation, and the executing subject of the method is a terminal. Wherein, the terminal may be a terminal having a data calculation function such as a computer.

[0051] Such as figure 1 As shown, the processing flow of the method may include the following steps:

[0052] In step 101, the preset design parameters, environmental parameters and top surface horizontal external loads of the excavated foundation are acquired.

[0053] In practice, before building the excavated foundation, technicians can design the parameters of the excavated foundation (i.e. design parameters), the design parameters can at least include the diamet...

Abstract

The invention discloses a method and device for detecting stability of an excavating foundation, and belongs to the technical field of electric transmission lines. The method comprises the steps of obtaining design parameters, environment parameters and top face horizontal outer loads of the preset excavating foundation; according to the design parameters, the environment parameters and the top face horizontal outer loads, determining anti-overturning moment and overturning moment of the excavating foundation; if the anti-overturning moment is larger than or equal to the overturning moment, judging that the excavating foundation meets the stability requirement, or, judging that the excavating foundation cannot meet the stability requirement. By the adoption of the method, the conditions that due to unreasonable design by designers, overturning is caused in the use process of the excavating foundation, a power foundation facility is damaged, and power supply is interrupted can be avoided.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a method and a device for detecting the stability of excavated foundations. Background technique [0002] In the transmission line project, in order to erect power infrastructure such as utility poles and wire racks, it is necessary to construct excavation infrastructure for fixing and supporting the power infrastructure in advance. When constructing the excavation infrastructure, engineers first need to dig a certain depth of foundation pit vertically on the ground, then place a steel skeleton in the foundation pit, and pour concrete to form the excavation infrastructure, and finally fix the power infrastructure on the excavation foundation on the facility. However, due to poor consideration by designers at the design stage, excavation infrastructure may overturn under the action of natural external forces (such as wind force) and the gravity of power lines and...
