The purpose of the work is to consider methods for calculating the forecast of groundwater backwater in the zone of influence of hydraulic structures. The analysis of analytical dependences of calculation of the forecast of groundwater backwater for various calculation schemes is carried out. For a homogeneous scheme of the geofiltration structure, a numerical model is proposed and a computational program for calculating the groundwater backwater is developed. It allows calculating the groundwater backwater from the channel at any time in the discrete mode. To simplify the solution of the problem of calculating the groundwater backwater, a computer program was created in the programming language Phyton Version 8.3 which quickly solves this hydrogeological problem. A possible range of geofiltration parameters is proposed for calculating the groundwater backwater near main channels. The adaptation and implementation of the software model was carried out for a specific object – the Bolshoy Stavropol channel-5, for which forecast calculations were made. The results of predictive calculations of groundwater backwater are the basis for the assessment of areas of possible flooding – the territory within which the level of ground water increases as a result of their backup by a hydraulic structure.

The use of cutoffs underneath the hydraulic structures is considered a safe solution to ensure the stability of hydraulic structure against uplift pressure and piping phenomenon in addition to the sliding and overturning forces of the water. These cutoffs are used at critical sections underneath the floor of hydraulic structure to substitute with their depths the horizontal lengths of the creep line of the hydraulic structure base. In this paper, the experimental method- by using electrical analogue model- was carried out to plot the flow net and study the efficiency of the front and rear faces of the cutoffs for dissipating the potential energy of the percolating water underneath the floor of hydraulic structure. An electrical analogue model which was used in this study consists of twenty five models with different depths of upstream and downstream cutoffs. After plotting the flow net for all models, it is concluded that the efficiency of the inner sides are less than that of the outer sides which were investigated before in this topic of this work that both faces reduction values in the uplift pressure are considered the same, where the efficiency of the outer face of upstream cutoff is (70.35) % and for the inner face is (29.64)%, while for the downstream cutoff the efficiency for the outer face is (76.21)% and for the inner face is (23.79)% .

There are six basic control items, land saving, energy saving, water saving, material saving, indoor environment and operation, among which, only material saving are related to structure design. We followed the green building design concept and the control items list in those standards during structure design of one of the residential area in Sino-Singapore Tianjin Eco-city, which consist of 15~18-story residential building connected to a large underground garage, as is shown below.

During the operation of pressure hydraulic structures, there is an objective need to ensure their safety and reliability. In the case of non-stationary loads on hydraulic structures, they can be either seriously damaged or destroyed. One of the non-stationary effects can be considered a directed explosion on the body of a hydraulic structure or in the immediate vicinity of it. At significant Mach numbers, the processes of excitation of the internal degrees of freedom of molecules, ionization and dissociation of gas molecules, and their recombination occur behind the shock wave front. The course of these processes is due to the almost tenfold compression of the gas at the time of the explosion and it’s heating relative to the room temperature of the order of 104 K. The use of approximate and numerical methods is a consequence of the difficulties associated with the need to solve nonlinear equations of gas dynamics, with the simultaneous use of relaxation equations and equations of chemical kinetics at the same time.

Studies investigating the benefits of green buildings can be approached by the affordance theory—the perceived properties of a thing that determine how it could possibly be used. This study focuses on the sustainable communication and education that a green building should provide. By applying the affordance theory, we examined whether a LEED-certified university campus building effectively communicates green design and sustainability to its users and if so, then how? We employed a questionnaire survey targeting campus users of a LEED-certified building by examining their awareness of the building's LEED status and perception of green design elements at multiple spatial scales, as well as their general knowledge on green building topics. We collected 177 questionnaires, of which 153 were qualified for statistical analysis. The results suggested that the building itself can afford to promote awareness among users, but cannot afford to educate users on general green building knowledge. We found that building users perceived green design at different spatial scales, preferring either product or space-related design. Our results indicate that future design should continue promoting the use of educational signage, which was found to be the most effective communicator of sustainability. The communication of green design to users with different spatial preferences remains a future research focus. Further studies on the innovative use of green building design as effective communicators are needed to promote sustainability education among the building users.

According to the characteristics and the development tendency of sea-crossing bridge construction, a concept of multi-purpose offshore operation platform for the construction of sea-crossing bridge is introduced in this paper. Meanwhile, the structure design plan and the features and advantages of the platform for sea-crossing bridge construction are listed in detail. The analysis shows that the multi-purpose offshore operation platform based on the modularization design concept could complete the tasks of sea-crossing bridge construction safely and efficiently. Due to the application of multi-purpose offshore operation platform, the construction cost of bridge should be reduced and the economy of project construction should be improved.

Construction Type

The green facades and living walls of vertical greenery systems (VGS) are gaining increasing importance as sustainable building design elements because they can improve the environmental impact of a building. The field could benefit from a comprehensive mapping out of VGS types, an improved classification and nomenclature system, and from linking the benefits to a specific construction type. Therefore, this research reviews existing VGS construction types and links associated benefits to them, clearly differentiating empirical from descriptive supporting data. The study adopted a scoping research review used for mapping a specific research field. A systematic literature review based on keywords identified 13 VGS construction types—four types of green facades, nine types of living walls, and ten benefits. Thermal performance, as a benefit of VGS, is the most broadly empirically explored benefit. Yet, further qualitative studies, including human perception of thermal comfort are needed. Improvements in air quality, reduction of noise, positive effects on hydrology, and visual benefits need much further empirical testing, as the current supporting data is mostly descriptive and based on the similarities with green roofs. The educational benefits of VGS has no supporting empirical evidence, while the social benefits have only been empirically evaluated through one identified study. Future progress of the field depends on the adoption of a clear VGS nomenclature system and further qualitative and quantitative empirical testing of VGS benefits, which should be clearly linked to a specific VGS construction type so that cross-comparison of studies is enabled.
