Description
Technical field
The present invention relates to a kind of portable soil experiment with measuring device.
Background technology
It is two weights in soil mechanics parameter detecting technical field, soil cohesion modulus and soil friction modulus
The soil characteristic parameter wanted.Test by carrying out pressure-depression, according to the soil mechanics formula of semi-empirical theory
Can be in the hope of the two parameter.It addition, cone index is the parameter representing resistance of soil, based on test data
Obtain the correlation model of soil cone index and the two parameter, it is also possible to calculate the two parameter.
Vehicle is being affected on general consolidation ground the most complicated, modal, is carrying out pressure-depression test difficulty
Degree is very big, because portable set is short of power, conducting oneself with dignity kicks the beam, and the vehicle installing vehicular equipment can

Bevel index is measured, the pressure of soft terrain comparative-depression is tested and compares soft terrain reduces compression distance
The test of non-fully pressure-depression.For comparability and the feasibility of guarantee test, guarantee test bar to greatest extent
The concordance of part, preferably completes cone index on an equipment and measures and pressure-depression test.In early days, use
Portable type bevameter carries out pressure-depression test, and it loads by compressed air, but power is unsatisfactory for requirement,
And portable cone index measuring instrument is by storage battery power supply, can the bigger degree of depth of injection, but its structure cannot be pacified
Dress pressing plate carries out pressure-depression to be tested, thus it is difficult to ensure that the comparability of test and feasibility.
