Osuwiska należą do najniebezpieczniejszych i najczęściej występujących geozagrożeń na terenie Polski. Bardzo ważną rolę w minimalizowaniu strat ma odpowiednie planowanie przestrzenne bazujące na dokładnych mapach podatności osuwiskowej terenu, które stanowią podstawę procesu określania zagrożenia, a następnie szacowania ryzyka. Celem artykułu jest pokazanie metody opracowania mapy podatności osuwiskowej wybranego obszaru Pogórza Dynowskiego pod kątem oceny zagrożenia osuwiskowego. Finalna mapa podatności na osuwanie obszaru badań została opracowana w skali lokalnej z wykorzystaniem indeksowej metody statystycznej. Poszczególne mapy czynników mających wpływ na osuwanie terenu uwzględniają: nachylenie zbocza; ekspozycję; bliskość cieków wodnych; geologię.

Landslides are among the most dangerous and common geohazards in Poland. A very important role in minimizing losses has a proper spatial planning based on accurate landslide susceptibility maps of the area, which are the basis of the process of determining the threat and then estimating the risk. The purpose of this article is to develop a landslide susceptibility map of a selected area of the Dynowskie Foothills in terms of landslide hazard assessment. The final landslide susceptibility map of the study area was developed on a local scale using the Index Statistical Method. The individual maps of factors affecting landslides were based on several thematic sections: slope slope, exposure, proximity to watercourses, geology.

Sheet piling is commonly used in various areas of special construction. Embedded in the ground before carrying out excavation works, sheet piling constitutes an enclosure and protection for the designed excavation. It is a temporary enclosure and protection for excavations made for communication structures, launch shafts built for microtunnel construction, etc. In order to assess the quality of the engineering works related to the construction of sheet piling, measurements were made of straightness and verticality of the sheet piling used for the technological chambers. The measurements concerned two technological chambers of 7.2 and 6.4 m height. Inventory measurements were made using a total station of 1” accuracy and a leveling staff with the appliance of the socalled projection method. The two technological chambers were built in the investment area called “Infrastructure construction for rainwater drainage, water supply and sanitary sewage collection from the John Paul II International Airport Kraków-Balice.”

The study of displacements of engineering structures using geodetic methods consists in determining the displacements of the structure in relation to the adopted reference system or in determining the geometry of individual structural elements or the entire structure. The geometry of tower objects is measured cyclically. In the case of telecommunications towers, the most common geometry research is the deviation of the tower axis and the turning angles of the tower at its individual levels. The article presents the methodology and results of the telecommunications tower geometry research obtained for a steel three-legged tower with a height of H = 32.11m. It is a steel tower with a typical structure. The structure in the projection is described on the plan of an equilateral triangle. In the corners of the tower there are curbs in the form of solid round bars. Angular observations were made in two positions of the telescope to selected points on the legs of the tower. The heights of the points on the foundations of the tower were obtained from measurements using the geometric leveling method. The heights of the points at each level of connecting the segments were determined by the trigonometric leveling method based on the measured zenith angles. The measurement points were related to the geometric axes of the tower legs at the connection points of individual segments. The tower displacement parameters were determined from geodetic measurements with the Theo010A theodolite.
