Embodiment Construction

[0036] In geotechnical engineering, the shear strength of soil is of great practical significance to engineering construction. The shear strength of the soil refers to the ultimate resistance of the soil to the shear stress generated by the external load. Under the action of external load, shear stress and shear deformation will occur in the soil. When at a certain point in the soil, the shear stress generated by the external force reaches the shear strength of the soil, the soil will slip along the direction of the shear stress, and the point will be sheared.

[0037] Clay is one of the important soil bodies. In order to solve the cumbersome calculation and low efficiency of the traditional method of judging whether clay is damaged by force, the present invention provides a method for judging whether clay is damaged by force by comparing intercepts. By means of drawing The size relationship of the cross-intercept in the figure can be intuitively obtained, and the comparison ...

Abstract

The invention relates to a method for judging whether clay is damaged by stress or not by comparing intercept. The method comprises the following steps: drawing a first intersection point of a Mohr-Coulomb strength envelope and a longitudinal axis and a second intersection point of the Mohr-Coulomb strength envelope and a transverse axis of the clay in an extreme equilibrium state in a two-dimensional coordinate system according to a shearing strength index of the clay; drawing the Mohr circle of which the circle center is on the horizontal axis in the two-dimensional coordinate system by taking the large principal stress and the small principal stress of the clay in a to-be-used state as two points on the Mohr circle respectively; drawing a tangent line on the Mohr circle by taking the first intersection point as a reference, and reversely extending the tangent line to obtain a third intersection point with the horizontal axis; comparing the first distance from the third intersectionpoint to the origin of the two-dimensional coordinate system with the second distance from the second intersection point to the origin of the two-dimensional coordinate system; and judging whether theclay is damaged by stress in a to-be-used state or not according to a comparison result. The method is simple, visual in expression and more efficient in stress state judgment.

Description

technical field [0001] The invention relates to geotechnical engineering, in particular to a method for judging whether clay is damaged by force by comparing intercepts. Background technique [0002] In geotechnical engineering, it is essential to understand the stress of rock and soil. Clay is one of the main types of soil. The traditional method of judging whether clay is damaged by force is usually by stress calculation or friction angle calculation. Judgment, but this method is computationally cumbersome and inefficient. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for judging whether clay is damaged by force by comparing intercepts, which solves the problems of tedious calculation and low efficiency in traditional methods. [0004] The present invention is realized by the following scheme: a method for judging whether clay is damaged by force by comparing intercepts, comprising the steps: [0005] A...
