The initial hanger tensions are first obtained through an iterative analysis by combining the girder-tower-only finite element(FE) model with the analytical program for shape finding of the spatial cable system. These initial hanger tensions, together with the corresponding cable coordinates and internal forces, are then included into the FE model of the total bridge system, the nonlinear analysis of which involves the optimization technique. Calculations are repeated until the optimization algorithm converges to the most optimal hanger tensions(i.e. the desired reasonable finished bridge state). The "temperature rigid arm" is introduced to offset the unavoidable initial deformations of the girder and tower, which are due to the huge axial forces originated from the main cable. Moreover, by changing the stiffness coefficient K in the girder-tower-only FE model, the stiffness proportion of the main girder, the tower or the cable subsystem in the whole structural system could be adjusted according to the design intentions. The effectiveness of the proposed method is examined and demonstrated by one simple tutorial example and one self-anchored suspension bridge.展开更多

The theological properties of the surrounding rock heavily affect second lining stability. In this work, we used laboratory triaxial compressive rheological limestone tests to study nonlinear creep damage characteristics of surrounding rock mass in construction projects. We established a nonlinear creep damage constitutive model for the rock mass, as well as a constitutive model numerical implementation made by programming. Second, we introduced a new foam concrete with higher compression performance and good ductility and studied its mechanical properties through uniaxial and triaxial tests. This concrete was used as the filling material for the reserved deformation layer between the primary support and second lining. Finally, we proposed a high efficiency and accuracy staged optimization method. The minimum reserved deformation layer thickness was established as the optimization goal, and the presence of plastic strain in the second lining after 100 years of surrounding rock creep was used as an evaluation index. Reserved deformation layer thickness optimization analysis reveals no plastic strain in the second lining when the reserved deformation minimum thickness layer is 28.50 cm. The results show that the new foam concrete used as a reserved deformation layer filling material can absorb creep deformation of surrounding rock mass, reduce second lining deformation that leads to plastic strain, and ensure long-term second lining stability.展开更多

In highway construction, the shortening or extension of the construction period will have a negative impact on the progress and quality of the project. This paper will analyze the current stage of the project construction and the problems existing in the project construction based on these factors. At present, the highway projects are mainly economic benefit analysis. The construction process does not conform to the relevant construction schedule formulated in advance, and there is a lack of supervision and management. Looking at the previous work experience, in the early stage of highway construction, a set of quality management system conforming to the project construction can be established, and a scientific construction plan can be planned. In addition, the purchase of construction materials can also be strictly controlled, and materials can be inspected and checked in the middle stage of construction, so as to prevent the occurrence of jerry-building or defective products, lay a solid foundation for the progress of highway construction and the quality of the project, and promote the long-term development of national highway construction.展开更多

Compared with other equipment, steam turbine has the characteristics of stronger power, longer service life and higher efficiency. At present, with the rapid development of science and technology in our country, the heat exchange equipment of steam turbine has also been developed rapidly at this stage. However, due to its complicated technology and significantly stronger functionality, this paper mainly analyzes and studies the actual conditions of deaerator and condenser, analyzes the effect of demineralized water temperature on dissolved oxygen, conducts the heating of demineralized water direct-makeup condenser and slag cooler, and puts forward the specific scheme to prevent the increase of dissolved oxygen in steam turbine and the measures and effects of rational use of heat energy, hoping to improve the safe operation efficiency and speed of the unit.展开更多
