Abstract

The invention discloses a novel method for measuring the area of a rock point load test fracture surface. The technical scheme is that the novel method comprises the steps of (1) preparing transparent area paper formed by small squares according to the area of 1mm*1mm and forming large squares according to the area of 10mm*10mm, (2) placing the transparent area paper on the rock point load test fracture surface, (3) drawing a fracture surface outline on the transparent area paper, and (4) counting the number of complete large area squares in the fracture surface outline and the number of small area squares in incomplete large area squares and calculating the area of the fracture surface. The novel method for measuring the area of the rock point load test fracture surface is simple and effective and makes up the shortages including time wasting and large error by means of a traditional measuring method, and the measuring accuracy of the point load test fracture surface and work efficiency are improved greatly.

Description

technical field [0001] The invention relates to a new method for measuring the size of the rupture surface under point load, which is suitable for measuring the size of the rupture surface in various geotechnical engineering point load tests. Background technique [0002] Rock mechanical strength index is one of the main technical parameters of engineering design involving rock. Whether the experimental data provided is correct or not has a great relationship with engineering safety and cost. In the past, the determination of rock strength has always been to select a small number of cores or rock blocks from the field and send them to the laboratory. According to the requirements of the rock test regulations, the test pieces are prepared with special machinery and tested on a press. It consumes a lot of manpower, material resources, and financial resources, which is very uneconomical; and, the number of specimens for routine tests is limited, which greatly affects the repres...
