Description
Technical field
The utility model relates to a kind of soil body wetting-drying circular tester, soil body three-dimensional is soaked under especially a kind of load action
The wetting-drying circular tester of water.
Background technique
Red clay is in arid season dehydration shrinkage, and rainy season absorbs water again is saturated expansion, and effect reciprocal in this way will lead to red glutinous
The variation of soil structures, native intensity gradually decrease, and finally cause the destruction of structures.But either strength reduction still deforms
It increases, structures unstable failure is the variation of filler mechanical index after all, and long-term drying and watering cycle effect is so that red clay
Mechanical characteristic reduces.Present day analog drying and watering cycle effect is all to be detached from stress after first sample is completed and carry out in advance
Then dry and wet is further applied load again to certain cycle-index.This method obviously not load and drying and watering cycle effect synchronize examine
Consider, exaggerates influence of the drying and watering cycle effect to red clay, have very big difference with actual conditions.Secondly, " highway soil test
Regulation " the CBR test of (JTG E40-2007) regulation in soaked and penetration process need at the top of sample loading support plate, it is therefore an objective to mould
Intend the vertical force that the material layer is generated by pavement structure weight, and provides that overlying burden is 50N (2.7kPa), but standardize to filling out
Expect that the value standard of CBR is then divided by the position that embankment soil fills, it is also different to fill burden pressure suffered by the difference of layer position.Therefore,
In order to simulate the real work state of filler, it is necessary to consider operating pressure suffered by roadbed different parts reality when test specimen is soaked.
Third, the water surface should be maintained at test specimen top surface or more about 25mm when regulation regulation test specimen is soaked, and compaction cylinder surrounding is closed, water

(top surface, bottom surface and side) immersion.For this purpose, immersion mode changes into lateral soaking.Finally, after regulation regulation CBR specimen molding
It answers soaked 4 to carry out simulation material round the clock and is in worst state burden pressure in use, this is a kind of than more conservative
Method causes moisture content bigger than normal, does not conform to the actual conditions, so as to cause part CBR value qualification roadbed filling it is misjudged be set to do not conform to
Lattice and it is discarded or mix lime cement processing etc., waste of resource while, also increases cost.To obtain the examination for meeting Practical Project
Parameter and index are tested, the wetting-drying circular tester and method for proposing that soil body three-dimensional is soaked under a kind of load action are necessary
's.
