In material, the main arch ring was made of MU60 coarse stones constructed with M15 mortar, the designed compressive strength value was , and designed the shear resisting value was , the modulus of elasticity was , gravity density γ was 25kN/m3, and M7.5~MU30 flaky mortar masonries were used for filling material
The reasons why the model was unable to accurately simulate the actual situation of the arch bridge can be concluded as follows: (1) in material, the materials chosen for the arch ring in the model were M10 and MU50 stones, while part of the old bridge could not reach the level, so the design value of the actual material strength might be low; (2) in size, different cross section sizes were used for the main arch rings of different arch bridge; (3) in load, the calculation model and the actual situation were different in the condition of both dead load and live load; (4) in calculation schematic diagram, the calculation model was simplified and some secondary factors were not considered, so that the calculation result tended to be not safe (e.g. the effect of shear force was not considered in the model ).

The system boundary of all materials (cement mortar, clay brick, wood doors, plastic-steel window (60 series), reinforced concrete, rebar, insulation materials etc.) are “from-cradle-to-gate”, involving raw materials acquisition, component production, related transport and energy generation processes [9-13].Meanwhile, the transportation of materials to construction site and construction processes are also considered in materials production phase. 2) Building operation phase.
The main conclusions are as follows: 1) For insulation system with different materials, material/energy consumption ratios of each flow to the total materials/energy consumption is consistent.

According to methodology for system science, water resources security pre-warning operation mechanism should be included logical issues, a matter of time and knowledge (science).
The main analysis steps are: data collection- system analysis – system design – system implementation, 4 steps in total. ① Data collection Through systematic surveys and monitoring, concerning water resources security pre-warning object history, current situation and development trends materials and data has to be collected hardly, at the same time, the collected data has to verify in order to ensure the scientific and authenticity of collected data. ② System design According to the nature of water resources security problem and the requirements of system objective, a number of water resources security pre-warning approaches have proposed, each approach has listed its function indicators and explained conditions required and the main advantages and disadvantages. ③ System analysis Through the establishment of system function and objective for analysis model, corresponding with water resources security pre-warning objective and evaluation standard and comparing with all pre-warning
Water resources security pre-warning is mainly used the theory of natural science, the scientific theory, hydrology and water resources science theory, 3S and computer science and technology.
On time, it reflects analysis steps for solving engineering problems which probably has been through for each work phase; on knowledge, water resources security pre-warning mainly use system natural science theory, natural science theory, hydrology and water resources science theory, 3S and computer science technology.
