At present, objects of responsibility (consequences) construction various classes, including SS-3 occurs in areas with possible manifestations of dangerous engineering-geological processes. One of such processes types is flooding. Based on the world experience, the main possibilities of using geosynthetic materials in various fields of construction are considered. Requirements for such materials and the conditions for their use are set out in European norms. An analysis of the program that is used to calculate drainage systems to meet force requirements in Ukraine is performed. These materials have good prospects for building in Ukraine with appropriate justification, considering the normative documents in force in our country.

The article describes a practice of using software system based on the finite element method for calculating shell foundations. It considers the peculiarities of the folded foundation interaction with subsoil mathematical modeling . It is found that during modeling, special attention should be paid to a purpose of the system initial parameters, to a choice of finite elements type, and to an optimal model of subsoil. Mathematical modeling of the folded foundation interaction with subsoil is performed under conditions of a plane problem. The foundation operation under various conditions of interaction with subsoil and with different stiffness parameters of the foundation is analyzed. Correlation between stiffness of a foundation structure and resulting equivalent stresses in subsoil under different conditions of interaction is determined. It is concluded that the obtained results represent a benchmark for subsequent calculations and modeling the interaction between a foundation and subsoil under a volumetric stressed condition.

The results of the executed economic comparison of foil-cement piles reinforcement use by vibroreinforced - vibroreinforced soil-cement piles are presented. The comparison is based on the results of piles bearing capacity by field tests. Considering the results of field tests two variants of piles foundation have been designed for residential building. Economical comparison is made for implementation effectiveness of reinforced and non-reinforced soil-cement piles at the piles calculated bearing capacity on the soil that is greater than the calculated bearing capacity by the material. .Economical comparison is made for implementation effectiveness of vibrated vibroreinforced soil-cement piles and bored piles at their calculated bearing capacity by the material at times greater than that on the soil. The obtained results and the determined economic effect are analyzed. The results of comparison are used for design and implemented in construction.

The analytical solutions for the determination of vertical displacements at any point of single-layer and multilayer soil compositions under filtration water flow influence, saline solutions presence and filtration considering soil changing filtration and deformation characteristics have been obtained. The mathematical models of soil filtration and the stress-deformed state from water-saturated ground massifs and bases deformations forecast under internal volumetric forces influence (hydrodynamic forces of the filtration flow, changes in the soils own weight) have been developed and substantiated. Numerical solutions of the corresponding boundary filtration problems and SDS of soil in regions with time-varying curvilinear boundary have been obtained for these mathematical models. They have enabled to perform water-saturated soils and bases deformations forecast under the change of hydrogeological conditions and man-made factors effect.

Відомо, що пластова вода є джерелом цінних мікроелементів, а саме йоду та брому. Підтверджено, що йод і бром ‒ продукт єдиного процесу трансформації органічної речовини, що відбувається при високих температурах і тисках. Для визначення вмісту йоду застосовано йодометричне визначення з використанням гіпохлориту як окиснювача. Цей метод дозволяє визначити кількість іонів йоду з точністю до 0,02 мг в аналізованому об’ємі води без підготовки. Установлено, що пластові води приурочені до пісковиків глибиною від 3 ‒ 14 до 30 м. Води представлено у вигляді розсолів. Визначено, що пластові води Чижівського та Більського родовищ можуть бути віднесені до йодо-бромного типу (бром, який складає щонайменше 25,0 мг/л, йод ‒ принаймні 5,0 мг/л). Згідно з дослідженням вод Серпухівського горизонту Чижівського родовища, виявлено експоненціальну залежність між середнім умістом йоду та вмістом солей у пластових водах свердловин № 39, 50 Чижівського родовища. Вивчено пластові води Більського родовища. Серпухівські відкладення товщиною 200 м представлено щільними пісковиками та алевролітами. У пластових водах свердловин 104 і 105 виявлено бром, йод у кількостях, доцільних для промислового видобутку. Пластова вода має мінералізацію близько176 г л. Дослідження показали, що води Чижівського й Більського родовищ можуть бути використані для промислового вилучення йоду та брому, оскільки вміст йоду перевищує 10 мг/л, а вміст брому досягає 599 мг/л. З’ясовано, що ці пластові води є цінною сировиною для вилучення корисних мікроелементів, які зараз втрачаються.

The method of curve surface discrete geometric modeling on the basis of two discrete frames superimpositions, formed by a static-geometric method, and on the basis of a single surface curve nodal points superimposition, also formed by static-geometric method, is considered. It has been determined that the suggested method allows to model balanced discrete structures formed on the specified contour nodes, as well as those passing through the specified nodal points without composing and solving equations systems.
