Eriyebilir Kayaçlarda, Yerkaymaları, Yeraltı ve Kırıklarının Jeoteknik ve Birleşik Jeofizik Yöntemlerle Belirlenmesi : Yat Limanı Antalya

Tie travertines observed along; shore Une of Antalya consists mî three steplike terraces
between sea level and SO© meters height. The fourth on© of these terraces takes place below the sea level
and e'tends afc least 90 Bieters seaward. There are karstic cavities, veins and Hndiergroiind water channels,
caused by chemical dissolution., fractures and gravitational slips in the pliocene aged travertine covers,
which have estimated thickness of 300 meters, Theree'iat domestic and touristic buildings over andin front
of the travertine cliff which is about SO meters high altong1 the shore Une. Under the influence of the
additional weight stack of contractions ami that of waste water, rate of fracturig, breaking off, folding*,
block sMpiiig and su&sidencing wr oa\img in are enhanced and them distraction clanger comes off, In order
to determine locations and dimensions of such occnrrances combined geophysical (resistivity, natural
polarization and seismic refraction), geological surveys, drillings ani laboratory e'peiiments on rock samples
were compleded. Opening of gracteres are between 0.1 to SO ein and sosue of them empty and some of them
saturated' with water. Travertene is hihly porous and COB tains caves In the rang« from 1 -10 mJ,
Geophysical anomaK.es of cracks, fractures and cavities have lower seisin!** wave velocity, lower resistivity
If saturated and higher resistivity If empty and larger ionization.
