Abstract

Abstract:

NoDig construction in the city might still encounter of difficulties. However, the difficulties or obstacles, which might cause schedule delays and damage to the pipes. This study considered different overcut range, sticking position, resistance, jacking force, and the location of jacks, etc., for the straight line and curved pipe-jacking. The ABAQUS finite element software was applied for threedimensional numerical simulations for straight line pipejacking with different difficult situations.

Key words: nodig, pipejacking, numerical analysis, overcut, stuck
