摘要

非明挖工法在都市施作时，常因困难地质(如卵砾石层)或障碍物而造成施工困难、工期延误或发生灾损。本文主要针对非明挖施工法里的管推进施工法(Pipe-jacking Method)，探讨管推进工法施工时可能遭遇的困难，以及施工困难状况下之管材土体互制行为。探讨的施工困难包括超挖、挤压、卡钻等问题。本研究针对超挖范围、卡钻位置、阻力大小以及推进力施加位置等，以ABAQUS有限元素软件进行三维数值仿真，探讨直线推进施工中的问题。

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
