Abstrakt

W pracy przedstawiono przykład interpretacji badań polowych, sondowań statycznych CPT oraz testów dylatometrem Marchettiego SDMT. Badania przeprowadzono na gruntach lessowych ma terenie Lublina. Wykonano 4 testy CPT oraz 4 sejsmiczne testy SDMT. Opisano metodę wyprowadzania parametrów geotechnicznych z badań polowych. W szczególności przeanalizowano formuły do obliczania modułu ściśliwości na podstawie oporu stożka q_c. Część z parametrów zinterpretowano z wykorzystaniem własnych formuł. Porównano wartości parametrów odkształceniowych oszacowanych odmiennymi metodami, dla różnych zakresów odkształceń.

Słowa kluczowe:

CPT, SDMT, less, moduł ściśliwości
