摘要
盾构管片裂缝的控制对隧道结构性能及防水至关重要,结合各行业规范裂缝的计算方法,同时进行盾构管片的抗弯能力试验,通过对试验裂缝数据与理论计算结果对比分析,得到与实际情况较为接近的盾构管片裂缝计算公式,为设计计算提供依据。
The control of cracks in segments is essential for tunnel structural performance and the waterproofing. This paper analyzes the difference between the theoretical calculation and the test,based on the bending resistance test,points out the calculation formula of the crack of the shield segment which is close to the actual situation,and presented as the references for the designs for shield tunnels.
