Analysis of Geological Conditions and Geotechnical Physical and Mechaniccal Properties 1.1 Introduction of Site Geological Conditions The site is located in the west extension section of Fujiang River and Shimaba Anticline and it is the south anticline which is open and symmetrical in its two sides with a dip angle of 2-5°.its structure is characteristic of gentle fold with few faults.
There is no complete underground water layer due to poor water content and therefore does not affect the slope control project. 1.2 Geotechnical Physical and Mechanics Properties According to the geotechnical experiment results and based on the local experience of slope control, the follwing parameters are suggested in Table 1.
To summarize, this natural slope is basicly stable at present. 2.3 Quantitative Analysis and Evaluation A: Parameters of geotechnical physical and mechanical properties The parametersare are selected from Table 1.
C: To analyze the stability of the natural slope close to the apartments to be constructed, this paper has section 4-4’ as the representative to verify the slope section and Fs=1.20 as the slope stability factor.
To evaluate the slope stability after the excavation for the construction of the above-mentioned apartments, we still adopt 4-4’ as the representative slope section for verification and Fs=1.20 as the slope stability factor.

Packing factor of perovskites is high, it is usually around 0.75 (e.g. 0.76 in LaMnO3).
Properties of iron-doped calcium titanate are similar to these of strontium titanate.
Properties of perovskite materials allow applying them as components of SOFCs.

Experiment 1.1 Physical properties of raw material According to Standard for Technical Requirements and Test Method of Sand and Crushed Stone(JGJ 52-2006),all kinds of physical properties of aggregate are shown in table 1 below.
Test results and analysis 2.1 Effect of mix proportioning method and residual mortar on RAC properties.
Relationship of the Splitting tensile strength is TRCS4properties According to the experimental observation and measurement, the slump range in 40 mm - 65 mm.As the increasement of recycled coarse aggregate content, the volume fraction of residual mortar increased and the actual sand ratio decreased, which leads to the RAC slump reduced. 2.2.1 Cube compressive strength According to Standard for Test Method of Mechanical Properties on Ordinary Concrete (GB/T 50081-2002) ,we respectively tested the density of concrete, slump, and 7 d, 28 d compressive strength; then test results are shown in Table 3: Table 3 Cube compressive strength and Fresh density of concrete Mix-ID RCA content

The suitable technological condition of preparing high strength composite ceramsite was given by studying the influence of the different mix proportions and different sintering systems on the properties of ceramsite.
The XRD(X Ray Diffraction) and SEM (Scanning Electron Microscope) analyses show that a large number of amorphous gel phases which affect the strength of ceramsite were produced in the process of sintering fly ash and waste glass and abundant even bubbles were formed inside of the ceramsite.
Some experimental studies about the preparation of the ceramsite using solid wastes, such as fly ash and sludge, were reported [7-10], but the products always had the poor mechanical property and high water absorbing rate.
The composite bubble-forming agent(A), the composite binder(B) and the roasting temperature(C) are selected as the three factors, the three levels of A are 5%, 10% and 15%, the three levels of B are 5%, 10% and 15%, the three levels of C are 1100°C, 1140°C and 1180°C.

During the nineties of XX century numerous works have delt with the determination of the third element location on the L12 lattice sites, because the mechanical properties of the trialuminides are strongly affected by the nearest neighbour atoms interaction [2, 3].
The obtained values of the fitting reliability factors are: RF=2.05% (R value for structure F parameter), RB=3.22% (R value for Bragg intensities) and overall profile factor RP=13.9%.
Reliability factors: RB = 2.05, RF = 3.22.

Ye et. al. [3] found that two major factors in the cast molding process which will affect the physical properties of the final PDMS mold, which are the vacuum degree in degassing phase and the curing temperature in solidifying phase.
The dimension accuracy of using pure PDMS mold was the worst, proving the effectiveness of carbon nanotube filling that improved the mechanical strength of PDMS.

All biofoam products were analyzed for physical properties (water absorption), heat resistance and biodegradability.
Even to some extent, degradable synthetic plastics such as polyesters and polyamides remain in the environment for a long time, depending on their post-use environmental factors such as oxygen, UV exposure, temperature, and more [2, 3].
This could include accelerated aging tests to simulate long-term exposure and assess how these factors affect the performance of the adhesive and the overall durability of the biofoam.
Conclusion This research has successfully conducted an in-depth examination of the impact of rice husk particle size on the physical and thermal properties of biofoam products.

Organizational resources encompass the company’s financial property, equipment and machinery, and most importantly, the knowledge, experience, and expertise of its human resources.
The operational activities may harshly affect the nature and environment by using natural resources and sparse raw materials, emitting toxic gases and breeding air, water, and soil contamination, and causing noise pollution.
They will also receive information from the related organizations as legislation or even feedback on how they affect the environment, how to react to the problems caused, implement corrective actions, and take preventive actions for future.
Moreover, economy affects and would be affected by industrial activities as they have a close mutual relationship with each other.
Therefore, the stability of a supply chain and consistency of its operations are closely related to economic and financial factors and vice versa.
