In this paper, the force status and a design method of single chain mooring system for shallow sea observation network are studied. With treating the link of a chain, steel drum and steel pipe as a rigid body, the recurrence model is established by using Newton's first law and the law of Moment equilibrium theorem. Via the simplified calculation of dichotomy searching, we determine the design parameters of mooring system, such as anchor model, anchor chain length, heavy ball quality under different water flow and wind conditions. We apply MATLAB to simulate the internal steady state of the system in the fixed scheme, water depth of buoy and swimming area to meet the decision-making needs, providing an idea for the actual scheme design of mooring system.

Reinforced concrete hyperbolic arch aqueduct's bent is arranged symmetrically on the main arch, load which is transferred from bent to main arch is more homogenous, it can improve force conditions of main arch, aqueduct is arranged on the bent, it also has the function of longitudinal beam. This paper adopts finite element method to carry out force analysis for hyperbolic arch aqueduct of Jinggu River third power station, considering aqueduct weight, water pressure and earthquake effect, etc. researching stress and deformation distribution law of reinforced concrete hyperbolic arch aqueduct.
