Abstract

The invention discloses multifunctional triaxial creep testing machine with soil body pulling, pressing, twisting and shearing functions, which structurally comprises a main body part, power supply equipment, an axial loading and measuring mechanism, a torque loading and measuring mechanism, a volume-changed water level controlling and measuring mechanism, an ambient pressure loading and measuring mechanism, a pore pressure measuring mechanism, a creeping and loading mechanism, an axial displacement measuring mechanism and a lubricating mechanism. A torque separator can apply any combined axial action and torque action; a multifunctional lever part not only can apply a tension action to a sample through a lever, but also can apply a pressure action to the sample through the lever; and a detachable split volume-changed measuring water jacket structure is remarkably changed on the aspect of soil body sample body-changed measurement. The machine provided by the invention is simple in structure, convenient to operate and high in accuracy rate and success rate.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering testing equipment, and relates to a multi-functional three-axis creep testing machine for soil tension, compression, torsional shearing. Background technique [0002] At present, the creep test of soil is mainly divided into two major research topics: microscopic and macroscopic. Among them, the research of microscopic creep test is to observe the microscopic structure of soil with the help of optical microscope or electronic scanning microscope, and use microscopic mechanism to To explain the creep characteristics of soil, but at present, only qualitative explanation can be done, and quantitative description is still difficult. [0003] The macroscopic creep test is divided into on-site creep test and indoor creep test. With the help of test instruments, through a series of test steps, the relationship between stress-strain-time of soil is studied to obtain the creep mechanical p...
