through-thickness tube
解釋
貫穿孔道-
Through simulating model tests of shield tunnel passing through the yellew river in the diversion project from south to north china, a systematic analysis on the primary factors affecting joint stiffness, including arrangement of joint bolt, thickness of annular packing of bolt, behavior and thickness of cushion material between two tube plates, magnitude of prestressing force of joint bolt and different stressed states at tube plate joint etc., are performed. the study results may provide reference for tube plate design of shield tunnel
通過南水北調穿黃盾構隧道模擬模型試驗，對影響接頭剛度的主要因素即連接螺栓的布置、螺栓墊圈的厚度、管片與管片之間墊層材料的性能和厚度、連接螺栓的預緊力的大小及管片接頭不同的受力狀態進行了系統的分析，為盾構隧道管片設計提供了參考。 -
