Since 1980s, a series studies about power transmission mechanism, material behavior and structure performance between CFRP tendon and concrete have been done by domestic and foreign scholars[1,2].The research results show:computing of bearing capacity of normal section about concrete member of prestressed with CFRP tendon submits to static balance condition of section, distort coordinated condition and the construction relationship between concrete and CFRP tendon; but the mechanical behavior and the energy dissipation performance are not so good as prestressed reinforcement concrete under load, and the failure of members is characterized by brittle fracture apparently.
The material property has been done before experiment ,which finds the test mean value of concrete cube compressive strength is 49.8 N/mm2 and HRB335 fy= 393.6 Mpa, fu=592 Mpa.

years, with the development of national economy and improvement of people's living standards, more and more attention on wheat quality, wheat production began gradually from quantity-based to quality, production and heavy-duty shift [1].Slurry is the maturity of the available fertilizer, rich in organic matter, humic acid, N, P, K and other nutrients and amino acids, vitamins, enzymes, trace elements and other active substances of life, and high availability of these nutrients can be quickly Absorption and utilization [2-5].So far, Domestic biogas sluny fertilizer study was focuses on nutrient substances, However, there may be a slurry of heavy metal absorption by crops into the food chain and accumulate in the agricultural environment and pollute agricultural and environmental risks [6].With the growing concern about the quality of agricultural ,the research in wheat and other staple food crops grown in the rational application of biogas slurry process related to food safety in China. 2 Materials

But the conventional geological mechanical model test is limited by the model size, causes similar material mechanical properties is difficult to satisfy the similar ratio, and at the same time, size effect also make the model test results reliability is affected certainly.
At home, China water conservancy water and electricity academy of sciences in a full discussion on the basis of completed in 2003 to LXJ - 4-450 large geotechnical centrifuge data acquisition system transformation. the system after the transformation uses the technology of LAN wireless transmission, and get good test results.
Recently for the Centrifugal model test of rapid drawdown of water table mainly considerate the situation of the displacement deformation in the process of slope failure, and to determine the size of the model, the selection of the test material and boundary effects will all affect the accuracy of the test.
