    1.2 SCOPE OF PERFORMED SURVEY 1.2. SCOPUL CERCETARILOR EFECTUATE

    The scope of this documentation is the determination of geological, hydrogeological and geotechnical conditions from the area, in order to supply the required data for the design and execution of the objectives modernization of the project TF Bordei Verde and Park 6 Bordei Verde, in order to be used in maximum security conditions.

    Documentatia are ca scop determinarea conditiilor geomorfologice, geologice si geotehnice, din perimetrul de teren cercetat, in scopul furnizarii datelor necesare pentru proiectarea si executarea obiectivelor afarente proiectului TF Bordei Verde si Parc 6 Bordei Verde, in vederea exploatarii obiectivelor ce se proiecteaza in conditii de maxima siguranta.

    The data which will be analyzed refers to the following aspects:

    Datele care vor fi analizate se refera la urmatoarele aspecte:

  • establish the general morphological, geological and hydro-geological conditions from the area;

    stabilirea conditiilor generale de morfologie, geologie si hidrogeologie din zona;

    framing the perimeter from the climatically and seismically grade perspective;

    incadrarea perimetrului din punct de vedere climatic si a gradului de seismicitate;

    determination of the lithological nature of the strata from the researched perimeter;

    determinarea naturii litologice a stratelor din perimetrul cercetat;

    specification of the local materials thickness and nature (soils, industrial waste and other filling materials);

    precizarea naturii si grosimii materialelor locale (pamanturi, deseuri industriale si alte materiale de umplutura);

    determination of the underground water level and eventual water seepages;

    determinarea nivelului apelor subterane si a eventualelor infiltratii de apa;

    determination of the physical mechanical parameters of the investigated soils;

    determinarea parametrilor fizico-mecanici ai pamanturilor investigate;

    soil rezisitivity measurements; masuratori de rezistivitate a solului;

    determination of some special natural conditions which may have a negative influence on the field stability and on the safety of the objectives exploitation.

    determinarea unor conditii naturale speciale care ar putea avea o influenta negativa asupra stabilitatii terenului si sigurantei in exploatare a obiectivelor;

    conclusions and general recommendations regarding the location of the objectives in the land;

    concluzii si recomandari generale privind amplasarea obiectivelor in teren;

    soils characteristics at digging, according with T.S 1995;

    incadrarea pamanturilor la sapatura, conform T.S.1995;

    The investigations in the perimeter indicated by the beneficiary together with the general designer were performed in February 2014

    Cercetarile in perimetrul stabilit de beneficiar impreuna cu proiectantul general s-au efectuat in februarie 2014.
