The bearing capacity fall sharply, and produce a large number of collapsible deformation, the formation of holes.
According to the technical specification for construction of highway roadbed, rice fields or perennial water zone, with fine grained soil filling height above 6 m and other areas filled soil or rock fill embankment height, when more than 20 m, according to the high fill embankment construction.
The bottom and the surface using fine grained soil or contain a small amount of mixed of gravel soil.

Lime rock reduced stone of continuous grain composition of Weifang, have a grade 5mm-20mm, sediment percentage 0.39%, air dry, native rock strength 55.6±8.9Mpa, apparent density ρoa=2.669g/cm3 , stacking density =1560 Kg/m3 .
The grain composition of yellow river sand meets the necessity of JGJ53-92.
On the other hand, by observing the SEM microstructure of sample interface, a number of crystal dense C-S-H gel grow or cover with fly ash particles surface, which reduces gap ration, enhances interface bond effect, and then improves mechanical properties of fly ash concrete.

The micrograph reveals that the pellet consists of small grains with estimated average grain size of 150 nm (figure 2).
The data are fitted by the Curie-Weiss (C-W) equation χ-1(T)=3k B (T-T CW )/(µ 2 effN)[25] where µeff is effective magnetic moment, N is Avogadro’s number, kB is Boltzmann constant and T CW is asymptotic paramagnetic Curie temperature, as shown by dashed line in Fig.5 .From this, the effective magnetic moment µeff and asymptotic paramagnetic Curie temperature TCW were estimated and found to be 4.87 µBand –158.0 K respectively for rare earth PrCrO3chromites.

Experimental Procedure The alloy Al-7Si-0.3Mg (A356, chemical composition given in Table 1) in combination with a small amount of the grain refiner AlTi5B1 and metallurgical sodium modification was cast in a so-called "French die", as shown in Fig. 1a.
As shown in Fig. 4a, the number of cycles to fracture is in general higher for specimens heat treated at high temperature (540°C and 545°C, 1 and 2h) than for those heat treated at 500°C (8h).
Ongoing fatigue crack propagation into eutectic regions, which intersect the same activated {111} slip band within the same grain, is slowed down by the barrier effect of the Si particles which have to be passed (Fig. 5a).

Materials (1) Cement :42.5 ordinary portland cement ; (2) Fly ash: Two ash; (3) River sand: The medium sand, fineness modulus of 2.27, water content is 0.67%; (4) Desalination of sea sand: Through test determination, chloride ion content is 0.01%, grain composition in the two district, fineness modulus of 2.62, water content is 3.51%; (5) Not washed sea sand: Through test determination, chloride ion content is 0.05%, grain composition in the two district, fineness modulus of 2.51, water content is 5.59%. 2.
The concrete mortar number classification in table1.

So, it can make full use of the characteristics of nano-particles and effectively inhibit nanometer grain growing up by adding nanometer ceramic particles to cast-penetrated layer.
Choosing CO2 sodium silicate sand, numbering the prefabricated layers after fire drying.
That can further optimize the microstructure of cast-penetrated layer, promote grain refinement, and make carbide evenly distributed in the form of granular, rods, and layered structure.

Related researches [6,7] found that the irreversible deformation was owing to the slip constraint between grains.
A large number of dimples can be observed in the broken zone in Fig. 7(c), 7(f).

Gaseous way should at least consider air immersion external exposure, surface sediment external exposure, internal radiation of inhaled air and eating vegetables, grain, milk, and meat.
Liquid way should at least consider shore sediments external exposure, water immersion external exposure, waterborne external exposure, drinking water internal radiation, internal radiation of ingestion of vegetables, grain and fruit due to contaminated water, internal radiation of ingestion of aquatic organisms, internal radiation of ingestion of animal products (meat, milk) due to contaminated crops and drinking water.
For all monitoring objects, the number, range, distance and other information about the representativeness of sample/monitoring points should be reviewed.

Lightweight construction, especially in the area of transportation engineering, is of increasing significance even with decreasing numbers of pieces.
