“…Many scholars, both at home and abroad, have focused on solving the concrete crack problem for long term. Despite a series of achievements [2][3][4][5][6][7][8], completely preventing crack initiation during construction is difficult in view of the randomness and particularity of ambient temperature, the complexity of crack formation, the uncertainty of various factors in the construction process, the lack of in-depth understanding of concrete material characteristics, the insufficient safety margin of engineering design, and imperfect cause formation mechanisms [9][10][11][12].…”

e focus on the development of China's vast hydropower resources has shifted to Tibet and other plateau regions. ese areas are high-altitude regions whose basic climatic characteristics are as follows: dry climate, significant differences in daily temperature, and strong solar radiation. If a dam is built under such special climate conditions, specific and strict temperature control and crack prevention measures should be taken. erefore, this study explores the temperature control standards, as well as temperature control and crack prevention measures, for concrete in high-altitude regions using three-dimensional finite element methods and based on the concrete gravity dam in Tibet in combination with the characteristics of material properties that are disadvantageous to temperature control and crack prevention. e temperature drop process can be optimized in time, and the temperature drop rate can be controlled to prevent excessive scale and temperature drop rates. Moreover, the temperature gradient can be spatially optimized, and thus, the differences in foundation temperatures, upper-and lower-layer temperatures, and internal and external temperatures can also be reduced. e research shows that the recommended temperature control and crack prevention measures can effectively reduce temperature stress.is study has a significant value as a reference for similar projects in highaltitude regions.

“…Although there was a temperature slope in the conduction, radiation and convection systems, the heat energy transfer proceeded when two systems were connected by a temperature difference. The heat flux due to solar radiation can be taken as a product of the absorptivity and total solar radiation [2,14,15]:…”

Thermal load is an important factor that must be taken into account during the procedure of bridge design and structural condition evaluation especially for those statically indeterminate bridges and cable-supported bridges. This paper presents an overview of current research and development activities in the field of thermal load in bridge, in which emphasis is placed on the thermal load models established by numerical analysis and field measurement. The theoretical formulations and boundary conditions of heat transfer in bridge are firstly outlined. And then, the states of the art of numerical solutions for temperature distribution in bridge including finite difference method and finite element method are reviewed in detail. Following that, the progress on thermal load in three types of representative bridges that are concrete bridge, steel-concrete composite bridge, and steel bridge based on field measurement data is discussed extensively. Finally, some existing problems and promising research efforts about thermal load in bridge are remarked.
