Background technique
Frozen soil is widely distributed in China, and seasonal frozen ground, ever-frozen ground summation account for about the 2/3 of China's national territorial area, frozen soil
The engineering construction in area is influenced more serious by frozen soil, therefore is of great significance to the research of physical-mechanical property of frozen soil.Have
Not in room temperature soil, the typical feature of frozen soil shows as water and freezes in the soil body, is mostly that original position is freezed in coarse-grained soil, occurs
Slighter frost heave；Phenomena such as will appear underground water suction, Taber ice formation, frozen fringle growth, cause soil more in fine grained soil
There is biggish frost-heaving deformation in body, and since poly- ice amount is more, spring easily occurs substantially melting here in frost-heaving deformation biggish location
It is heavy, seriously affect the safety of permafrost region roadbed, building.
The reason of frost heave occurs first is that water congeals into ice in soil volume increases 9%, but this part frost heaving amount is little；It is former
Therefore second is that the soil body is in freezing process, underground water being aspirated, the fractional condensation of ice first occurs in the soil body, subsequent frozen fringle starts to grow,
Generate larger frost-heaving deformation.In this process, water migrates in the soil body, causes different parts in soil to show different aqueous
Amount, the quantitative test of the water content have great importance to the explanation of analysis and Frost heaving mechanism that body frost heaving deforms.
Currently, test frozen soil in water content there are several types of methods: method 1 is the in-situ test carried out at the scene, more
It is carried out using the method for embedded moisture transducer；Method 2 is tested by indoor frost heave test.The above method respectively has
Advantage and disadvantage are discussed below:
First for cost, the inbuilt method higher cost of moisture transducer, the market price of a sensor is 5000
Member or so, the data that obtain multiple spot need to bury multiple sensors, and expense is higher；And used in the process of indoor frost heave test
Aluminium box, baking oven, balance are most common instrument in laboratory, convenient test.Secondly assume to be all made of moisture transducer to carry out
Test, then on-the-spot test more meets actual temperature condition for test site on-the-spot test and indoor model test, but
Test result is more random, in test process after moisture transducer is buried in field, in long-term observation process
It is less to its maintenance, and since the time of natural freezing experience is long, therefore the spoilage of sensor is also higher, cannot ensure whole
Data can acquire acquisition；The method of indoor test is although carried out certain simplification to it, and test condition is stablized, sample
Small, the testing time shortens, and sensor degradation rate is low, and the quantity of valid data is more.
Therefore, right except for the large-scale in-situ test for being specially provided with observation field for many years in the test of Frozen Ground Area
Water translocation research mostly uses indoor frost heave test.But during the test, an existing common problem is exactly frost heave test
Soil sample after the completion, due to congelation to bond between soil sample and sample barrel very securely, if test specimen tube using pair
Film or trivalvular form are opened, sampling is relatively easy, but the test specimen tube of split film or three plate films, during soil sample freezes moisturizing
Easily there is infiltration phenomenon and influences experimental result；But if using closed cylinder-shaped test specimen tube, in soil sample frozen state
Under, sample is taken out, sampling difficulty is larger.In addition, the soil sample taken out, need to be layered at once and carry out water content test, freeze
Knot soil sample intensity is very high, and it is larger that the layering of soil sample cuts difficulty；Axe is cut according to conventional knife and strikes mode, the time required to cutting
It is long, it will lead to the variation in temperature field in soil sample, moisture field, be affected to test result, how to guarantee fast sampling and cut sample
Excessively lost to avoid temperature be similar experimental design emphasis.Furthermore the mode that knife cuts that axe strikes, which can not be realized, cuts position to sample
