The measuring method is convenient and fast. By adopting the measuring method, measured parameters are comprehensive, and the operating efficiency is high.
Description
Technical field
The utility model relates to a kind of self-operated measuring unit of soil body physical property index, belongs to soil body physical property index measuring method and surveying instrument field thereof.
Background technology
Some physical propertys of soil depend mainly on the proportionate relationship of forming shared volume of native solid particle, the water in the hole and this three-phase of gas and matter (weight) amount, reflect that the index of this relation is referred to as the physical property index of soil.The physical property index of soil not only can be described the physical property and its residing state of soil, and, reflect native mechanical property to a certain extent.So in numerous project implementing process, the physical property index of understanding soil is very important.
Soil body physical property index can be divided into two types: one type is must be through test determination, like density, specific gravity of soil partical and water percentage, is called direct indicator; Another kind of according to the direct indicator conversion, like void ratio, saturation degree, dry density etc., be called indirect index.Soil body physical property index commonly used has nine, is respectively natural density ρ, specific gravity of soil partical Gs, water percentage ω, void ratio e, porosity n, saturation degree Sr, the dry density ρ of soil
d, saturated density ρ
Sat, buoyant density ρ '.
At present, different soil body physical property index is to measure respectively through the different test of design implementation, and the test principle of different experiment with measuring institute foundations is different, and general observational record data with the naked eye.For example, when measuring specific gravity of soil partical, often adopt pycnometer method to measure according to the equal-volume substitution principle.In advance pycnometer is filled with pure water, weighing bottle adds the quality of water.Pack the some grams of oven-dried soil in this sky pycnometer into then; Add pure water again to full; Weighing bottle adds the quality that soil adds water, according to the computes specific gravity of soil partical:
In the formula: m
1---bottle adds the quality of water;
m
2---bottle adds the quality that water adds soil;
m
s---the quality of oven-dried soil.
Again for example, measuring water percentage is oven drying method according to the normal method that adopts of water percentage definition, weighs up the quality of natural wet soil earlier, be placed on then in the baking oven, at 100 ℃--oven dry 105 ℃ of normal temperature under, claim the dry ground quality, then according to water percentage definition calculating water percentage.
So these test methods are not enough below obviously existing: (1) is owing to the test principle of measuring soil body physical property index all is not quite similar, so soil body physical property index of every survey; The experiment with measuring that just needs a correspondence of design; Complex operation step, workload is big, inefficiency; (2) most of test figures adopt manual record, and automaticity is low, and precision is not enough.
