Problems solved by technology

In the National Standard of the People's Republic of China "Technical Code for Building Slope Engineering" (GB 2013), the active rock pressure calculation method for rock slopes damaged by sliding along gently inclined outwardly weak structural planes is given, but this method only It is applicable to the case of rock slope failure due to shear slip. For the above-mentioned second category—rock slope with sliding and rotation failure along the steep outward-dipping weak structural plane, this formula is not applicable, because the The formula cannot consider the rotational failure of the slope

Abstract

The invention discloses a method for calculating the active rock pressure when a rock slope is damaged along a steep outward-dipping weak structural plane. Calculation parameters of the rock slope; Step 2, carry out stress analysis on the rock slope damaged along the steep outward-dipping weak structural plane; Step 3, establish a linear programming model for solving the active rock pressure of the rock slope; Step 4. Numerical solution of the linear programming model to obtain the limit value of active rock pressure. The invention is rigorous in theory, high in calculation accuracy, and simple in engineering application, and can be applied to the design of rock slope retaining walls, etc., and can provide reliable and accurate active rock pressure data for support structure design.

Description

technical field [0001] The invention relates to a calculation method for rock slope active rock pressure, belonging to the technical field of rock slope stability analysis. Background technique [0002] In recent years, a large number of rock slope projects have appeared in the process of large-scale infrastructure construction in my country, and many rock slopes need to take support measures to ensure the stability of the slope; therefore, in the rock slope support Whether the active rock pressure can be accurately calculated when designing the protective structure becomes more important. [0003] In slope engineering, a kind of rock slope that is damaged along the outwardly weak structural plane is often encountered (such as figure 1 shown), the calculation of the active rock pressure of this type of rock slope has a certain degree of complexity for the following reasons: (1) When the outwardly inclined structural plane is gently inclined (the inclination angle of the weak...
