Background technology

Saturated hydraulic conductivity in soil, when referring to soil by water saturation, passes through the water of unit area in the unit interval.Differently Area's soil property is different, and orographic condition difference, different soils depth and vegetation pattern influence etc. are all made to saturated hydraulic conductivity in soil Into different degrees of influence, in addition, also relevant with the soil texture, structure, salt content, water content etc..Determine soil saturation Hydraulic conductivity has important scientific meaning to the further understanding of soil physical properties.

It is indoor core cutter method to determine saturated hydraulic conductivity in soil most common method at present.Its principle is to take undisturbed soil with cutting ring Sample, after immersion, under unit hydraulic pressure gradient, according to Darcy's law, is tried to achieve by perpendicular to the unit soil section of water (flow) direction The saturated hydraulic conductivity or infiltration coefficient of long-pending water velocity, referred to as soil.Conventional chambers core cutter method determination step is：Taken with cutting ring Undisturbed soil sample, takes back interior and removes upper lid, lower cover is changed into after the eyelet bottom equipped with a metafiltration paper, immersion saturation, takes idle loop knife Bonded with cutting ring sample with adhesive plaster melten gel, be put into that funnel is upper and lower to be accepted with beaker.Idle loop knife upward adds water, and funnel drips out Beginning timing, the water in beaker is measured every certain time with graduated cylinder, until stable stopping.Soil saturation is calculated by Darcy's law Hydraulic conductivity.

Conventional indoor core cutter method, it is higher with the requirement of adhesive plaster melten gel adhesion process in the sample that saturation is reached to immersion, And taken time and effort when being determined to batch sample, also there is drainage in continuous mode, cause determination data bigger than normal, as a result not Reliably.

According to indoor core cutter method when carrying out Multi-example measure, there are two methods.One kind is to make many collar knife systems to come Determine simultaneously, but the randomness artificially added water in continuous mode causes the head of multiple samples to be pressed and unequal.It is another to be Determine after a sample, continued the measure of next sample, the Systematic Errors for causing different sample rooms to determine are larger.Both Method all consumes substantial amounts of manpower and time.

Meanwhile, there is the random error of artificial reading in indoor core cutter method, cause to survey to oozing out in the reading process of water Determine the precision reduction of result, this error randomness increases and taken time and effort especially when being determined to batch sample.
