Mass concrete technology has been widely used in the construction field. In engineering construction, the quality and construction technology of mass concrete are directly related to the quality of the projects. Thus, before the construction of mass concrete, a series of experiments should be made, and also the key points of the construction technology should be strictly followed in the construction process. In this paper, by taking the application of mass concrete in stadium project as an example, the test before the construction of mass concrete and the technical application in the construction are analyzed.

Subway shield lining segments are highly sensitive to peripheral soil disturbance. Shield displacement may destroy the whole structure which can not be repaired, and directly affects the subway operation safety at the worst. Therefore, it is necessary to reasonably determine the construction technology, in order to avoid the unfavorable influences caused by construction disturbance. According to the pile-board subgrade scheme which is adopted by the comparison of schemes, also considering the high risk of over-shallow-embedded metro construction, we put forward the key construction technique of pile-board subgrade, including: technique of casing tube bored pile, construction process of pile-board structure and monitoring of settlement and deformation which are important to guide the similar projects.

In order to analyze the effect of heat preservation, the heat preservation technology of detail structure, such as decorative lines of external walls, edge beam and edge column, windows, balcony and laying position of air conditioner, have been well treated under the system of thin plastered external wall based on EPS. Moreover, the technical-economy benefits of detail structure treatments have been analyzed by comparing with those without detail structure treatment. The results show that better heat preservation and economy benefits would be created by detail structure treatment, which could provide good reference for similar construction process.

Abstract. In the past 2 decades a new modern scaling technique has emerged from the highly developed theory on the Lie group of transformations. This new method has been applied by engineers to several problems in hydrology and hydraulics, including but not limited to overland flow, groundwater dynamics, sediment transport, and open channel hydraulics. This study attempts to clarify the relationship this new technology has with the classical scaling method based on dimensional analysis, non-dimensionalization, and the Vaschy–Buckingham-Π theorem. Key points of the Lie group theory, and the application of the Lie scaling transformation, are outlined and a comparison is made with two classical scaling models through two examples: unconfined groundwater flow and contaminant transport. The Lie scaling method produces an invariant scaling transformation of the prototype variables, which ensures the dynamics between the model and prototype systems will be preserved. Lie scaling can also be used to determine the conditions under which a complete model is dynamically, kinematically, and geometrically similar to the prototype phenomenon. Similarities between the Lie and classical scaling methods are explained, and the relative strengths and weaknesses of the techniques are discussed.
