In this  study, pile integrity testing data of 187 piles in  two close sites located in Buyukcekmece, Istanbul are  analyzed. The test method utilized in this project is  the sonic echo method. The aim of this study is to  detect occurrence of discontinuities along the pile  axis. As the test data reflect the change in  impedance, possible impedance diversity due to soil  conditions must be known beforehand. In this manner,  impedance difference caused by the discontinuities in  the pile is distinguished and acquired. Using  TNOWAVE''s SITWAVE application, pile integrity testing  is simulated and signal matching procedure is  executed. In order to achieve reliable results using  SITWAVE, sufficient soil investigation must be  performed to determine the soil layers and soil  parameters properly. In the signal matching process,  the test signal data are matched with the reference  signal data simulated by the software.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844331370\"\u003e\u003ch3\u003eDetermination of Pile Quality Using Low Strain Integrity Testing and Automatic Signal Matching\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844331370","offer_id":39469974028381,"sku":"9783844331370","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/3b674527-f5c1-4185-a2de-49b042118ece.jpg?v=1770529680","url":"https:\/\/shop.autorenwelt.de\/products\/pile-integrity-testing-von-tolga-y-ozudogru","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
