Abstrakty

PL

Trójwymiarowy model numeryczny służący do analizy procesu drążenia tunelu tarczą wyrównanych ciśnień gruntowych (ang. Earth Pressure Balance – EPB). Automatyzacja tworzenia modelu numerycznego oraz odczytywania wyników analiz przez wykorzystanie autorskiego skryptu Python. Weryfikacja modelu na rzeczywistym przypadku niebieskiej linii metra projektu MRTA w Bangkoku. Ilościowe określenie wpływu zwiększonej objętości urabianego gruntu, ciśnienia wypełnienia pustki w ogonie tarczy oraz ciśnienia podparcia przodka na deformacje ośrodka gruntowego oraz siły wewnętrzne w obudowie tunelu. Rozwój mechanizmów w czasie oraz ich zmiana wywołana działaniem procesów technologicznych.

EN

A three-dimensional numerical model for the analysis of tunnelling carried out with the Earth Pressure Balance (EPB) shield. The Python script for automation of numerical modelling and extraction of results. Verification of the introduced model based on the MRTA blue line project in Bangkok. Quantification of the effects related with the excessive overcut, tail void backfilling pressure and face support pressure. Development of induced mechanisms in time together with their modifications due to manipulation of the technology parameters.
