Research and Application of Model Materials Based on Soft Rock Model Test

Abstract

In consideration of few researches on model materials of soft rock tunnel model test, and the problems such as high price of raw material, difficult availability of materials in market, and weak universality existing in the materials which can be used as reference, this paper researches and develops the model materials with low price, wide source, and strong universality. The application result shows that the developed model materials can meet soft rock model test requirements, and they can be reused within 3 months.

Study on Testing Methods for Thermophysical Properties of Materials

“…These methods mainly include: hot line method, the thermal probe method, tropical method, pulse plane heat source method, step plane heat source method and hot plate method. The thermal line method can measure the larger sample by inserting a line in the sample to apply a constant heating power, make its temperature rise [7]. According to the test form it can be divided into cross thermal line, parallel thermal line, and heat resistance line.…”
