Embodiment Construction

[0034] Such as Figure 1-Figure 3 As shown, a method for analyzing the opening field and seepage of rock fractures under different pressures, the method includes the following steps:

[0035] Step 1: Select the required type of rock, split the rock to obtain a split sample 1;

[0036] Step 2: Cut the split sample 1 into a cuboid sample of a suitable size according to the crack direction;

[0037] Step 3: Separate the cuboid sample along the splitting crack and divide it into two rock samples, which are respectively recorded as: sample A and sample B;

[0038] Step 4: Drop the filler (liquid silica gel) on the cracked surface 9 of the sample A, put the sample A and the sample B together into a rectangular sample 8, and mark the relative position of the joint for recording (relative position Record, should be along the direction perpendicular to the fracture surface), to ensure that the relative position does not change when multiple times of splicing;

[0039] Step 5: Apply ...

Abstract

A method for analyzing the opening field and seepage conditions of rock fissures under different pressures, the method comprising the following steps: step 1: obtaining a split sample; step 2: cutting; step 3: sample A and sample B; Step 4: Drop the filler on the fracture surface of sample A; Step 5: Get the fracture surface at a normal pressure of F 1 The 3D model of the initial situation; Step 6: Apply the normal force F 1 ;Step 7: Get the normal pressure of the fracture surface as F 1 The three-dimensional model of the initial flow situation at the time; step 8: get the normal pressure of the fracture surface at F 1 The opening field and the seepage situation at that time; Step 9: Repeat the above steps 5-8 to obtain the opening field and seepage situation of the fracture surface under different normal pressures. The method for analyzing the opening field and seepage conditions of rock fissures under different pressures provided by the invention can better obtain the real opening and seepage conditions of the rock opening field under different pressure conditions.

Description

technical field [0001] The invention relates to the technical fields of geotechnical exploration and construction, in particular to a method for analyzing the opening field and seepage conditions of rock fissures under different pressures. Background technique [0002] In many tunnel projects, underground pipe corridors, and mineral development projects, groundwater seepage has had a considerable impact on construction, greatly slowing down construction progress, and even bringing serious safety problems. Now there is an urgent need for a method that can analyze the distribution and opening of a certain rock fracture under different pressures, and obtain the analysis method of the rock fracture under different pressures, so as to provide information for engineering exploration, seepage plugging, and construction. etc. to provide references to ensure the safety of life and property. Contents of the invention [0003] The technical problem to be solved by the present invent...
