The invention discloses combine hydro-thermal analysis test method in a kind of soil.Soil sample is impregnated by hydrogen peroxide and distilled water handles etc. repeatedly to remove organic matter, chiltern, inferior soil and electrolyte, test condition is that soil sample grinds compared with small particle, test soil sample amount 20mg, appropriate close dress sample, 10 DEG C/min of heating rate, capping and do not cover and do and compare and test program is used uniformly weighing-initial latency before measurement starts；Different type combination water can be marked off by this method and improves experimental result accuracy, solved due to soil sample or since experiment needs specially treated such as 250 DEG C of high temperature drying that test result is led to problems such as to be difficult to mark off different type combination water. |
