Abstract

The invention relates to a method for calculating the base bearing capacity of a dump based on the limit upper limit method, belonging to the technical field of calculating and analyzing the base bearing capacity of a dump in open-pit mine engineering. The method for calculating the base bearing capacity of the dump based on the limit upper limit method comprises the following steps: Step 1, determining the physical and mechanical property parameters of the artificial piles and the base of the dump; 2, calculating the limit value of the bearing capacity of the foundation base according to theprinciple of the limit analysis upper limit method; 3, dividing that plastic zone into a plurality of soil strips with incline interface based on the principle of the limit analysis upper limit method, wherein each soil strip is regarded as a rigid body, and obtaining the basic equation of the limit analysis upper limit method for calculate the base bearing capacity of the dump; and Step 4, determining the limit load and the stability coefficient of the limit equilibrium. The method for calculating the base bearing capacity of the dump based on the limit upper limit method solves the technicalproblem that the accuracy of the analysis and measurement of the base bearing capacity is insufficient, the result is accurate, and the utilization space of the base bearing capacity of the dump is improved.

Description

technical field [0001] The invention relates to the technical field of calculation, analysis and calculation of the base bearing capacity of a dump site in open-pit mine engineering, in particular to a method for calculating the base load capacity of a dump site based on a limit upper limit method. Background technique [0002] The construction of dumps is an important part of mine production. Dumps, also known as waste rock dumps, are huge artificial accumulations, and there are serious safety problems. The instability of the dump will lead to mine soil disasters and major engineering accidents, which will not only affect the normal production of the mine, but also cause the mine to suffer huge economic losses. According to incomplete statistics, in general examples of landslides in mine dumps, 32% to 40% of landslides are caused by basement instability due to insufficient base bearing capacity. Previous research on dump sites was based on the stability of dump sites Howev...
