Problems solved by technology

[0003] Rock coupling creep refers to the phenomenon that the stress increases with time. Water is an important factor affecting the instability of rock creep and cracking. It is not easy to fix the rock during the hydraulic coupling creep test. The test is completed under the condition of providing stable water pressure or pressurization, and it is not easy to adjust, which increases the difficulty of the test

Abstract

The invention discloses rock hydraulic coupling creep testing equipment, which comprises a lower shell, an upper shell, a limiting mechanism and a testing mechanism. The limiting mechanism comprises a stand column, a supporting plate, a first spring, a guide rod and a sealing gasket. The testing mechanism comprises a protruding block, a pressing plate and a fixing plate. According to the rock hydraulic coupling creep testing equipment, the shell is arranged, so that rock can be placed and can be fixed, a test experiment can be smoothly carried out conveniently, a rock storage space can be sealed, and a hydraulic coupling creep test can be conveniently carried out; and the hydraulic coupling creep testing equipment is provided with the fixing plate and the pressing plate, so that the interior of the shell can be pressurized, the pressure can be adjusted according to the hydraulic coupling creep test requirement, effective proceeding of the test experiment is ensured, the operation difficulty is reduced, and the practicability of the testing device is improved.

Description

technical field [0001] The present application relates to a test device, in particular to a rock hydraulic coupled creep test device. Background technique [0002] Creep of rock refers to the phenomenon that the strain of rock increases with time under the condition of keeping the stress constant. The creep of rock under geological conditions can produce considerable deformation, but the required stress is not necessarily large. , the creep with time can be roughly divided into three stages: initial creep or transitional creep, the strain increases with time, but the increasing speed gradually slows down; steady-state creep or steady creep, the strain increases with time Increase at a constant speed, this stage is longer; accelerated creep, the strain increases rapidly with time, until it reaches the rupture point, the greater the stress, the shorter the total creep time; the smaller the stress, the longer the total creep time. However, each material has a minimum stress va...
