Mass concrete is widely being used in the construction field, especially for the foundation of super high-rise building. In the initial stage of pouring completion of mass concrete, lots of heat generated from the cement hydration will lead to a high temperature inside of concrete. When the temperature difference between the inner and outer of concrete exceeds the limited value, thermal stress will be greater than the tensile strength of concrete, which may cause hazardous penetrating cracks of the structure. To ensure the safety and durability of concrete structure, necessary measures should be taken to control the temperature rise and construction quality of concrete. Taking a super high-rise building project as an example, this paper introduces several effective solutions to resolve above problems. The technical measures such as enhancing the concrete quality, controlling temperature rise, strengthening temperature monitoring would be detailed illustrated. Meanwhile, valuable suggestions achieved from this practical project are proposed in order to guide the structural design and on-site construction of similar projects.

With the continuous improvement of China’s construction technology, the application of mass concrete structures is increasingly popular in various structures in order to meet the requirements of structure and function, such as tall buildings, dams, railways and highways. There are all kinds of cracks in construction process because of the big cross section. There are many reasons to form cracks, but temperature is the most common cause. It is vital to the construction quality of mass concrete that the hydration heat, especially the peak value of temperature rise, is calculated in advance and precautions are implement in construction process accordingly. In this article, the calculation formula modified is derived through analyzing the common calculation formulas of mass concrete, the actual measurement results and the influencing factors of temperature rise.

This article presents a GIS-aided visibility and dominance analysis used for a visual-impact assessment of a planned high-rise building located in a central area in Trondheim, Norway. The visibility analysis calculates fields of intervisibility between the high-rise building and locations in the urban landscape. Visual obstacles such as existing buildings and trees are included. The dominance analysis adds to the visibility analysis a measure of how visually dominant the high-rise building would be. The dominance measure is based on the distance to the building and how much of the building would be visible from any observation point. The result is an assessment of visibility and dominance throughout the entire study area as opposed to using photomontages for assessing visibility and dominance from single standpoints.
