Partially ephemeral streams are complex objects that can still be used for water supply or irrigation of agricultural land. The problem of such streams is poorly studied, because the influence of various environmental factors complicates carrying out any experiments. Also it is not possible to make their full classification due to their very strong variability not only on a particular geographical belt, but also within separate areas of the river. All this undoubtedly complicates the task of the designers when designing the system. Creation of laboratory models, allowing us to evaluate the possibilities of a spring use for the purpose of water supply, is very promising. These watercourses have a large amount of suspended sediments, so it is not possible to use the standard scheme of water using of the coastal and fluvial water intake structures. It is proposed to organize the fight with the sediments in the flow chart of primary clarifiers, which will perform the function of settling suspensions, to facilitate the work of water treatment facilities. Also the creation of artificial prop is useful in order to achieve the required level of water in a watercourse for water organization. If under the bottom of the river there is underground water, and the permeability of the soil is good, it is possible to arrange the withdrawal of water through infiltration intakes, by setting the filter under the bottom of the watercourse with its connection to filter, from which the water will climb to submersible pumps. Additional filtration through the soil of the river bottom allows not using the scheme sumps, which significantly reduces the cost of epy incoming water treatment.

The Far North of Russia has a strong power generation potential. Future hydraulic power engineering projects may include construction of major power generating plants in south Yakutia. The core elements of the proposed projects will comprise dams about200 meters high.The authors substantiate construction of a masonry dam in severe climatic conditions of the Far Northern region of Russia. The structural solution represents a masonry dam having an impervious element, or a wide internal membrane, made of soil and cement concrete. This element is to protect the soil-free membrane from any thermal effects. The authors provide their analysis of the deflected mode of the dam, if its height is equal to 226 m. The findings have proven that the membrane made of soil and concrete cement will be in the state of compression. Therefore, the authors believe that the proposed design of the dam structure is reliable enough.

FEATURES OF FORMATION OF THE STRESS-STRAIN STATE OF SYMMETRIC AND ASYMMETRIC RIVER VALLEYS

River valleys take freakish shapes. In mountainous areas, river beds take the forms of canyons, gorges and valleys. In turn, a valley may be symmetric or asymmetric. D.G. Panov is the developer of the valley classification. The valley is a linearly extended relief pattern similar to Latin letter “V” in shape. Let’s consider the two valleys from the viewpoint of geomechanics. In research, it is necessary to define the optimal position of an arch dam with account for its stress-strain state that may develop in the course of its construction and further operation. As an example, we took a hypothetical mountain river having a high-pressure hydroelectric power plant (HPP) with a concrete arch dam.The first series of calculations was aimed at the study of the process of development of the stress-strain state of the massif based on the symmetrical valley slope inclination angle. The second series of calculations was aimed at the study of development of the stress-strained state of the massif depending on slope inclination angle of an asymmetric valley. The following angle values were randomly chosen: 10°, 15°, 20°, 25°,30°. Additional analysis of a slope having the inclination angles of 35°, 37° and40° was performed. At 35°, the slope was steady with a big safety factor, at 37°, the slope was steady, too, but the safety factor was below 10 %, and at 40°, the slope collapsed. The Mora Pendent model was employed for modeling purposes.

The article describes the results of a comprehensive survey of the bridge structure in Dubna. The survey was performed to determine the load capacity and maintainability of the bridge structures for the period prior to the repair, as well as to collect the information necessary to update the draft decision and the right strategy of major repairs. The growing needs of the city Dubna, which several times increased the operational loading of the bridge structures, and no major repairs since the construction, led to the need of restricting the traffic capacity of the only transportation artery. By the time of the survey in November 2011, contraflow over the bridge and the restricted traffic of more than 8 t was organized, which resulted in tense atmosphere in the city.The authors studied the historical data and design features of the supporting structures of the bridge. Particular attention was paid to the state of load-bearing structures of the bridge and their deformability. The strength characteristics were studied. The authors analyzed the results of calculations in order to determine the carrying capacity of the bridge structures with the test loads. It turned out that the carrying capacity of the bridge is sufficient for load accommodation. However, in accordance with the regulations, the bridge does not meet modern requirements for the travel width. It was recommended to maintain contraflow and to provide operational loads of the class H-10 (i.e. platoons with GVW of 10 t and the presence of a single vehicle in a platoon with GVW of 13 t) until the major repairs. After major repairs with restoration of bearings, waterproofing, water disposal system, replacing the bed, repair of the protective layer, it will be possible for single vehicles weighing up to 25 t to pass over the bridge.

Introduction. Presented the approach to the create a filtration model of the base of the hydroelectric system, built by mathematical and statistical generalization of the results of mass filtration testing of the rock mass. In the proposed filtration model, the rock base is divided into several engineering-geological design elements with different permeability. Materials and methods. The most common approach to build the model is determine the points of the array hydraulic pumping and injection of water into the well, as well as by calculation, when the filtration coefficient of the array is calculated on the parameters of cracks. Results. One of the advantages of the proposed form of the filtration model of the rocky foundation of the hydroelectric complex is the form and method of its construction by means of mathematical and statistical generalization of the results of mass filtration testing of the rock massif. Conclusions. In of civil engineering the filtration model of the base of the hydraulic unit can be built on the results of the poson filtration testing of drilling wells at certain points of the rock mass. The difficult task of dividing the base massif into zones with different water permeability is solved on the basis of a geological-genetic approach in combination with mathematical and statistical analysis. The practical significance of this filtration model is that it can be used to design reliable hydraulic structures while ensuring stability and minimizing filtration losses.
