Problems solved by technology

However, due to various factors such as the fluidity and heterogeneity of the broken rock mass and the layered distribution and mixed distribution of the broken rock mass of various lithologies after the collapse of the rock formation, the seepage field, temperature field, stress field, and strain field of the broken rock mass are caused. The multi-field coupling problem is extremely complex, and the research methods using theory and numerical simulation have significant limitations, and research work must be carried out on the basis of reliable data from laboratory tests
[0004] However, the existing broken rock mass test devices and methods cannot realize the scientific experiment work in this innovative strategic research field, mainly due to the following aspects: 1. the broken rock mass cannot be compacted, seepage, heat exchanged, and powered at the same time. Coupling test; ②The essence of the enhanced geothermal mining method is that the hot dry rock in the upper part after blasting provides a stable heat source, and the broken rock mass that falls down increases the heat exchange area. The direct heating of the whole body cannot simulate the heat exchange process between the complete rock mass and the bro

Abstract

The invention discloses a fractured rock mass multi-field coupling test and monitoring system. Multi-field coupling test data of a seepage field, a temperature field, a stress field, a strain field and the like of the caved broken rock mass under complex disturbance conditions such as a static load, an impact load, a long-time stable load, a periodic pulse, a vibration load, an actually measured disturbance load and the like can be accurately obtained; the complete rock body lithology of different rock samples can be conveniently studied; rock-rock and water-rock heat exchange rules, fracturedrock mass seepage field distribution rules and fractured rock mass internal stress field evolution rules of complete rock mass heat source temperature, fractured rock mass lithology, particle size, gradation, combined distribution forms and the like under the conditions of different applied loads, disturbance conditions, seepage fluid initial temperature, seepage fluid initial pressure and the like are determined; and more accurate test data are provided for the research of a deep geothermal exploitation technology under a complex load condition according to a multi-field coupling action mechanism of a stress field, a deformation field, a seepage field, a temperature field and the like.

Description

technical field [0001] The invention relates to a broken rock mass test system, in particular to a compaction and permeability multi-field coupling test and monitoring system for simulating complex in-situ disturbances and impact loads of broken rock mass, belonging to geotechnical engineering test technology and equipment fields. Background technique [0002] As a clean energy source, geothermal energy is receiving increasing attention all over the world. Geothermal energy is stored underground and is not affected by climatic conditions. It can be used as base load energy or peak load energy. From the perspective of its development and utilization costs, geothermal energy has the characteristics of low cost, less land occupation, and good stability. Compared with other renewable energy sources, it has more development potential. Deep high-temperature geothermal resources suitable for power generation are widely distributed in southern Tibet, western Yunnan and western Sic...
