地铁盾构管片弯曲变形特性试验研究

Test Research on the Bending Resistance of Segment for Subway Shield Tunnel

介绍了北京地铁五号线工程盾构管片的抗弯能力试验,根据试验数据对管片的抗弯能力做了分析,给出弯矩与变形能力曲线,并对管片弯曲能力计算方法做了理论分析,通过试验数据与理论计算结果比较分析,给出工程用弯曲能力计算公式.

this paper describes the test on the bending resistance of segment for the 5th Beijing subway tunnel. Using the experimental data, we obtaine the curve line of moment_bending resistance and analyze the bending resistance of segment. We also establishes the method of calculating the bending resistance theoretically, and presents the formula for the bending resistance of segment by analyzing calculating and the experimental results.
