Method of calculating total process deformation curve of rock mass

Abstract

The invention provides a method of calculating a total process deformation curve of rock mass. The method comprises obtaining structure data of the rock mass, calculating total process deformation data of the rock mass and drawing a total process stress-drain curve of the rock mass. With the weak link strength theory of rock mass mechanics as the basis, the invention obtains structure data of therock mass by comprehensively considering geological conditions of the rock mass, and through SMRM computing software, calculates total process deformation data of the rock mass; and finally, through SMRM computing software again, draws total process deformation data of the rock mass into the total process stress-strain curve of the rock mass, so as to provide rock mass information closer to authentic structure and environmental state for engineering construction and offer important reference data for engineering construction, such that engineering construction design is more reasonable.

Description

technical field [0001] The invention relates to the field of deformation testing of engineering rock mass, in particular to a calculation method for the deformation curve of the whole process of rock mass. Background technique [0002] The deformation curve of rock mass is an important index to evaluate the stability of engineering rock mass, which affects the safety of engineering construction and reasonable construction design. Therefore, the deformation of rock mass has always been a hot spot in the field of rock mass engineering. Due to the existence of a large number of structural surfaces and other fillings in the rock mass, the deformation of the rock mass is mainly the deformation of the rock mass structure and the deformation of the rock material. At present, the deformation curve of the whole process of the rock mass cannot be obtained through experiments. Part of the deformation curve is mainly carried out through the in-situ test, but the damage of the in-situ t...

Problems solved by technology

Due to the existence of a large number of structural surfaces and other fillings in the rock mass, the deformation of the rock mass is mainly the deformation of the rock mass structure and the deformation of the rock material. At present, the deformation curve of the whole process of the rock mass cannot be obtained through experiments. Part of the deformation curve is mainly carried out through the in-situ test, but the damage of the in-situ test specimen requires a large load, the test is expensive, the cycle is long, the test equipment is bulky, and the operation is complicated, etc.

In addition, the in-situ test of rock mass is much smaller than that of engineering rock mass, and the measured parameters can only represent the mechanical parameters of rock mass within a certain range.
