Zbrojenie gruntu, najogólniej rzecz biorąc, polega na wprowadzeniu do niego elementów wykonanych z innego materiału, charakteryzujących się odpowiednimi, pożądanymi parametrami, przede wszystkim: przyczepnością, wytrzymałością i trwałością.

Generally, soil reinforcement consists in placing in the soil elements made of other material characterised by adequate required parameters, most of all by adhesiveness, strength, and durability.

The results of GPS static measurements, conducted in the first measurement campaign at the reference and check points should be adopted as the values of reference for future observation results. The measurement procedures, developed for the first campaign, should be followed in further measurements. The measurement equipment (pole for forced centring of a GPS aerial, GPS aerial, GPS receiver) assigned to each point during the first campaign, should be used each time at the check points. The same calculation procedure should be followed in the analysis of the GPS observation data in future measurement campaigns. If the need to change the calculation procedure is justified, the calculations from previous measurement campaigns should be absolutely redone.

The data obtained in the precise levelling performed by the Przedsiębiorstwo Geologiczno - Geodezyjne ,"Geoprojekt - Gdańsk", as well as the material analyses, indicate the need to conduct further observations of dislocations in the Main and Old City of Gdańsk in the next years, in intervals of at least six months, controlled by independent fundamental altitude points. The results of GPS static measurements at reference and check points, conducted during the first year, should be taken as reference values for the measurements conducted in subsequent years. The differences in the results from consecutive years will indicate the existence of vertical and horizontal movements of the earth's surface, where the City of Gdansk is situated. The check points, stabilised with fundamental altitude points, will be used to monitor the settlement of historical tenement houses in Gdańsk. Measurement of horizontal and vertical deformations of the earth surface in the areas where valuable objects of our cultural heritage are situated will make it possible to detect potential threats and to take action to prevent considerable damage.

Omówiono technologię budowy ścian szczelinowych umożliwiających wykonywanie głębokich wykopów w bezpośrednim sąsiedztwie płytko posadowionych budynków. Omówiono technologię pomiarów osiadań i pionowych deformacji fundamentów budynków p o d wpływem wykonywania w sąsiedztwie głębokich wykopów. Zilustrowano na przykładzie zależność między osiadaniami i pionowymi deformacjami fundamentów budynków a pracami ziemnymi i budowlanymi w sąsiadującym z nimi głębokim wykopie.

Technology o f building slotted walls, used for protection during deep earthworks, is outlined in the article. The authors presented technology o f geodetic control measurements, used for determining: 1) vertical displacements o f benchmarks placed on the carrying walls o f the existing buildings, which are located close to the construction area o f the underground garages or buildings with several underground storeys; 2) horizontal displacements o f points placed on the slotted walls due to allevation, caused by deepening o f excavation surrounded by these walls. The problems related to the range o f control measurements, location o f observation stands, reference and checked points, were discussed in the article. The authors presented the example illustrating relations between the determined displacements of benchmarks, vertical displacements and changes o f inclinations o f foundations o f the existing buildings and particular phases o f earthworks and construction works in the deep excavation located close to these buildings. In was emphasized, that deformations o f foundations o f the existing buildings can appear not only due to deepening o f excavation, but also earlier as a result o f construction and bolting o f slotted wall in close neighbourhood o f these buildings.
