Abstract

The invention relates to a large-sized fluid-solid-heat multi-field coupling test loading system. The large-sized fluid-solid-heat multi-field coupling test loading system consists of a loading framework main body, a loading platform, a pressure chamber inlet-outlet platform and a data acquisition system. The large-sized fluid-solid-heat multi-field coupling test loading system has the following advantages: firstly, the test loading space is changed by virtue of an adjustable central crossbeam, and the multi-field coupling test for test samples of different types and different sizes can be realized by selecting different pressure chambers for different test samples of different types; secondly, under the situation that the pressure chamber is not used, a hydraulic crack test for concrete and rock under high water pressure can be carried out, and a conventional material parameter of the material can be determined; thirdly, by adopting a pressure chamber hoisting device and a wheel inlet-outlet platform device, the replacement of different test samples and different pressure chambers can be conveniently realized; fourthly, by adopting the data acquisition device and data storage software, data such as water pressure, confining pressure, axial pressure and temperature variation can be fully automatically acquired, displayed and stored in real time in the whole process without interfering with each other.

Description

technical field [0001] The invention relates to a large-scale fluid-solid-thermal multi-field coupling test loading system suitable for soil materials, concrete and rocks. Background technique [0002] Since the “Twelfth Five-Year Plan” and the large-scale implementation of the western development strategy, the construction of large-scale water conservancy and hydropower projects in my country has continued to develop, and a number of 300m-level earth-rock dams and concrete dams are under construction or have been put into operation. [0003] Affected by the climate environment, design, construction and maintenance, cracks in the dam are almost inevitable. In order to ensure the normal operation of reservoirs and dams, the mechanism of crack initiation and propagation under conditions of variable temperature, high water pressure, and complex stress has become a research hotspot in the current academic circle. A large number of scholars are committed to carrying out a large ...
