Inverted siphon is a common conveyance structure，in order to have a clear understanding for stress and deformation distribution of inverted siphon structure, researching mechanical characteristics of inverted siphon structure. Precast inverted siphon has advantage of quick construction speed, easy control of construction quality, etc. This paper adopts the universal finite element calculating software to simulate and calculate precast inverted siphon, and gets stress and deformation distribution of inverted siphon under the most unfavorable conditions, and provides beneficial reference to the design and application for the reinforced concrete precast inverted siphon project. The results showed that, Liziwan inverted siphon engineering adopts precast inverted siphon is safe and economic, in the construction and operating process, inverted siphon's stress and deformation values are smaller, the stress and deformation values can meet engineering requirements.

Abstract-The numerical simulation study for water conveyance of inverted siphon on water security is of great significance. The inverted siphon is thin-walled concrete structure, and cracks will appear according to temperature loads. Generally speaking, the temperature difference between the internal and external and the basic difference of temperature are considered as the main factors influencing the cracks. Static analysis of inverted siphon structure is the foundation of design and construction, includes the calculation and analysis of stress and strain of inverted siphon structure. The stress and strain of inverted siphon structure not only are the index of inverted siphon structure rigidity, but also are the basis of identifying whether the inverted siphon structural damage occur. Using the basic theories of temperature and stress field of concrete, this paper adopts 3d finite element to simulate and calculate Shaba inverted siphon, and gets stress and deformation distribution of inverted siphon during operation period. The results show that inverted siphon structure is economic and reasonable, can meet the stiffness requirement, and can provide beneficial reference to the design and construction for other inverted siphon structure.

Abstract-The inverted siphon straw is pressure water pipeline which convey cannel water through valley, river, road, depression, or other channels, and it is a kind of channel cross building, is one of the most important buildings in irrigation engineering.In order to the stress and deformation distribution of the inverted siphon structure have a clear understanding, studies the stress characteristics of inverted siphon structure. This paper uses the general finite element calculation software of Xin'an Pu ditch burying of inverted siphon structure do the analysis by three dimensional finite element simulation, studied the stress an deformation distribution in the construction and operation cases of inverted siphon structure, provides a useful reference for the design and construction of reinforced concrete trench buried type of inverted siphon structure. The analysis results show that, Xin'an Pu inverted siphon project using reinforced concrete trench buried structure is safe, economic, inverted siphon Straw in the construction and operation process the stress and deformation are small, and can satisfy the engineering requirements.
